Excellent comparison video. It's good to see someone just showing images and comparing systems in use without a lot of hyperbole or the usual marketing talking points. Very useful.
Really nice comparison, as fair to both systems as is practical. Both wonderful systems; that OM system is pretty amazing. Thank you for taking the time to post this video.
The sort of comparison I love. Thanks. I've never tried Sony, but needed to "go light" so moved from Nikon DSLR to Nikon mirrorless (didn't like the autofocus), so then Canon (first R6, then R7) but just couldn't get on with either. Now used OM-1 for two months, and I just love it.
Glad to hear your assessment, including the preference of OM-1 over R7. I'm still using the D500, and I may stay there for years to come. However, I am more and more likely to 'eventually' pick up the OM-1 and a long lens, which would probably be the 100-400 or 300f4, since I can't justify the 150-400 for personal use.
@@danielosborne8228 D500 was my last DSLR, and I absolutely loved it, but with a 200-500 on it was just too heavy. Mirrorless seemed the way, but after three major kit changes, this is the first time I really think my new kit outclasses the D500.
I did the same albeit going from the R7 to the EM1X, a bulkier camera but it was €750 used and it's a stepping stone into the system. The R7 felt like a toy and I hated the controls, I wasn't bowled over by the images coming out of a supposedly high spec ASPC. Before that I shot Sony FF cameras. I'm in love with the Olympus system now and the lenses are so compact, affordable and rugged. To get a camera from another system with the same features you're looking at thousands just for the body and then there's the price of FF lenses with any kind of weather sealing. It's an insane amount to invest just for a bit more low light performance and boken
@@sourcebased I don’t think that lens will become substantially cheaper any time soon even 2nd hand. There is just still too much demand va supply and they apparently cannot produce them in high volumes.
I got mine 20 % cheaper second hand from a camera dealer in Sweden when the lens was just 5 month old but the price now second hand is a lot higher at least the one on MPB right now. It's a really good lens and if you compare the price with other similar pro lenses in full format It's really cheap if you can say that 8000 dollar or more is cheap... 😉
I have both too the Sony a1 and the om1 but I am new to the micro 4/3 however It has a lot of in camera like the live composite, focus stacking built in ND filter to mention a few,and I just found the button on front by the lens lets you do a custom w/b so easy,
I have the Same opinion! The OM System SET is the better choice for many reasons. Other Wildlife Photographers, like Mike Lane and Daniel J Cox have the same opinion and also chose the OM set. They made very interesting videos about that. Thank you to bring this out. It can help many people to choose better!
Thank you Dennis for a fair and down-to-basics comparison video. The Olympus 150-400 is a fine lens with a complex design. Interesting you mention it is well balanced, i.e. does not feel front-heavy. I only regret hesitating before acquiring the lens, already in possession of the great 300/F4. Acquiring the OM-1 as an upgrade over from the E-M1.2/E-M1X was a no-brainer in comparison.
thanks for the lovely shots and the nice comparison. i am olympus user since 2004 in the digital era, was so happy never thought i had a problem until they started to hear about the superiority of FF, got the Nikon D810 (acutely it was a gift form my uncle) yes got many stunning results, just as i get form my olympus e5 + Sigma 50-500 mm, but both were too heavy to handhold. in the mirrorless world and when the Zuiko 300 mm f4 came the battle was over, and the D810 + Nikkor 100-500 mm became history.
I use to use Canon gear. In 2019, when I got back into photography I bought into the mft (micro 4/3) system as it was finally at the point where it was good enough for my needs and still using that system. Before getting the OM-1, I looked and Canon, SONY. I was not interested in full frame bodies. The OM-1 is a great camera and the price is still reasonable. I have recently purchases the Olympus 150-400mm (stick in major sticker shock). Very impressed with the lens and looking forward to making great images with it over the years.
Great comparison, I have the OM-1 but sadly I can't afford the 150 to 400. I do have the 100 to 400 leica which for it's price and waite is still a good combination.
Nice video. Thank you. Your comments reminds and reinforce why in 2007 when my film camera gave up the ghost and I moved to digital why I decided against full frame and went with Olympus. Lenses are more important then camera and Olympus make some of the very best and have done for the last fifty years. Ultimately the picture quality will be better with full frame but to properly exploit the full frame sensor one has to use their pro lenses and when you are talking about photographing wildlife that usually means fast long primes and zooms and the costs of these are very expensive. The Olympus pro lenses and back then the semi pro line were the deciding factor for myself because they were the equal or better then practically anything full frame could offer at the same focal lengths and they were much cheaper. With the arrival of the OM-1 there is a body which can exploit them and provide a genuine alternative to the more expensive full frame offering from Canon, Nikon and Sony, particularly when paired with a lens like the 150-400, which is genuinely revolutionary, for less then £10,000.00 Sterling. A comparable Full frame system would cost around £30,000.00 Sterling. Yes, it would perform in ultimate terms better then the OM system but in the majority of cases one would not notice the difference in picture quality and the OM system would be considerably cheaper, lighter and more versatile. If however, you know that most of your photography is going to be taken at high iso (3200) and above and you have very deep pockets and you are willing to carry heavy fast lenses around and mostly work with a tripod and a heavy monopod and gimbal, by all means stick with full frame. For the rest of us, give the system a try using the try before you buy loan scheme. I suspect you will be pleasantly surprised, particularly if you keep the subject large in the frame so you don’t have to crop excessively, exploit the image stabilisation and keep the iso as close to the base setting of 200 as you can, set up the exposure blinker alerts and focus peaking and bird or animal detection and exposure as far to the right as you can before the blinker’s indicates you are clipping the highlights. In post you can recover 3 stops of over and under exposure if you make a mess of things in camera. Most of all, have fun.
@@DennisJacobsenWildlife that’s just it, ….an opinion wrapped in a series of constraints and the conclusion can only be that you use what’s best the task in hand within the budget available and your videos emphasise the point that’s it’s a personal choice. Well done.
Now on my last day of a 4 week bicycle tour with the OM1 (40-150 2.8 pro, 100-400 and mc14), I shot 55000 pictures, got amazing shots of Kingfishers, Sea Eagles, Ospreys, Purper Herons, Sterns, Little Egrits, etc in sometimes harsh weather conditions (tropical heat, heavy rain and summer storm Poly). The OM-system is great for such conditions having the camera on a sling while cycling to be ready for every opportunity. Also used it on water splashing canoe trips several times. Love the system...
Thanks for making this video. I have been tempted to buy the om1 and 150-400, this video really helps. I tried the 150-400 at a show it felt so light I thought it wasn't real, but it was.
Its a great set! just remember its not in the league of the newer FF mirrorless systems in IQ .. BUT it does make some great photos and videos i my opinion :)
@@DennisJacobsenWildlife I have A1+200-600 and also R7+100-400is ii. The R7 has some of the features the OM-1 has but they don't work well due to the rolling shutter. I pray A1 will add procapture but I fear my prayers will go unanswered.
@@daviddouglasuk I to think nothing more come to the A1 :/ I sold all my Sony gear adn go with OM system this year and see what happens next in the marked! :) im interested to see what the Canon R1 will deliver when its released.
Thanks for this video and confirming I made the right decision in purchasing the OM1 and MZuiko 150-400 pro lens. And trust me, if could afford it and have the stamina to carry the a1 and the 600mm, I would have gone in that direction. In the back of my mind, I had a gut feeling that in purchasing the A1 with the Sony 200-600mm, I would have missed out on the picture quality vs the OM1 and the MZuiko lens for photos. I don't shoot video as much. So, thanks, you have confirmed that image quality comes from what type of glass you put in front of the camera and not as much as the number of pixels. Also, I can confirm that the om1 can shoot in super low light with iso of 6400 and 10,000 in a pounding rain and produce quality images after post processing.
On my opinion both systems are great. For wildlife an Macro I would prefer the OM. For sports and daily purpose the A1 is IMHO the better option. There is no perfect system for all situation. If you do a lot of cropping - the megapixels of the A1 are great. If you would like good results OOC then the OM setup will satisfy you. Another thing is size an weight. This is the habitat of OM. Best thing you can do is: go to your local camera store, lend out the system you prefer and try it out yourselve, before you buy it. I have Sony AND Olympus and this combination is perfect for me.
Great video comparison - shows OM-1 really punches above its weight class. I shot last year's COTA F1 and this year's COTA MotoGP with OM-1 and 150-400. My friend uses A1, although with 100-400 and not 200-600, and we both agree that the OM-1 pictures compared very well with the A1 - particularly in sharpness. I did end up selling the 150-400. Great lens, but I don't shoot sports and wildlife often enough to justify. Same justification that kept me from buying an A1. Beast of a camera, but after using the OM-1, I am more than satisfied with image quality and AF performance.
My first though was how well the 200-600 did compared to a 4x more expensive lens of the OM. A little sharpening on the 200-600 images and they are quite similar.
Actually the A1 has 50mp vs the OM-1s 20MP. Taking into account the focal length differences, the OM-1 only has 35MP at 600mm, and it's noticeably out resolving the Sony setup.
@@stevemurnan1702 What?, The sensor on the A1 can not replicate sharpness & details that isn't there -aka fed by the lens. There is a konsensus that lenses are the key for catching sharp and detailed images. Lesser quality lens on the OM body would have shown the real differense between a pro and non pro lens. Here is a budget lens compared to a pro lens and it keeps up quite well imo. If bodies were tested surely the A1 Should had carried the 400mm f/2.8 GM og 600mm f/4.0 then there's another story.
@@arildhagen3820 agreed on your point to a degree but for wildlife photography, for proper composition it would be a huge advantage to shoot with a pro zoom lens than a fixed one. I don’t know this but does Sony have a pro zoom available? And if Sony ever come up with a 200-600 pro lens I would bet than many would trade in their 600mm.
@@joeret2896 yes, the 100-400 GM is a pro lens. They also have som normal range zoom but are missing some in the longer range where they only have primes
FACE OFF time! I came from 200-600 A7rIVa and have the same findings. Everyone is in different stages of their photography journey, I outgrew the 200-600 very quickly, which makes the pricing irrelevant when you need to upgrade after only 6 months. I then learnt not to go for the next logical upgrade step, but to skip 2 steps (if you know what I mean) so you can grow and develop into it. But at the top end of town, the law of diminishing returns is very painful on the wallet.
The Sony kit is a great kit but it appears the OM seemed to kick it's butt. I know end result is going to favor the Sony kit for greater ability in the A1 and A2 area. But the OM is definitely more portable . That Zuiko lense is outstanding. Thanks.
I have the A1 with the 600GM and the OM-1 with the 300Pro. The Sony 600 and the Olympus 300 are both fantastic lenses. The Sony takes a 2x particularly well but the Olympus is surprisingly good too with the 2x. Bird eye tracking is good on both, but general subject tracking on the OM-1 is two generations behind. It is definitely easier to go out with the Olympus. The 600GM is a better lens than the Sony zoom as one would expect. It is the best 600f4 I have ever used. Olympus desperately needs better general tracking and a few more pixels would be nice.
I'd agree with you on the OM-1general subject tracking. That's the weak spot but specific subject tracking (bird, animal etc) are pretty good and not much different from my R5.
I’d love to get another one of these comparing an a7iv with the 200-600 vs the om-1 with the 100-400 as the cost for each pair is much less at circa 3k
Thanks for the comparison. I have used the 200-600mm for a long time, and I find it significantly sharper at F8. I only use F6.3 when im challenged by the light. In good light - always F8. I think cost over performance you get a lot in the OM system. Im a Sony user, but think I will look more into the OM system.
Thanks for your comment Jon. The OM system gear are super good .. and if they can tweak the AF to be a little more consistent in BIF/Action it will be super nice
You can achieve almost the same results if you apply appropriate sharpening to the raw files in post-processing, and the Sony also has less noise. Considering the price (4x lower then 150-400mm) the 200-600mm is an amazingly good lens and a great value.
Thanks for doing this comparison. You make it harder for me to resist from getting Oly 150-400mm F4.5 lens :-). This is somewhat to be expected even though I have seen some people kept arguing the other way. OM-1 package would cost more though. But I agree, I would go for the OM-1 package.
Thanks for the comparison. I would be interested in comparing the Olympus 150-400 vs the Sony 100-400. I love the A1 (although an update is needed) but the Olympus 150-400 is obviously a fantastic lens and clearly sharper than the Sony 200-600. But for 3.75 times the price it better be.
Thanks RM Clark :) i have the the 100-400 and its a great lens but for small birds on larger distances the Olympus 150-400 is better but also more expensive! :)
The 300F4 is even (slightly) sharper but without the flexibility of a zoom but at a fraction of the price. Also, the 300 with the 1.4 is my perfect combo for BIF. I carry a second body with the Leica 50-200 for closer shots or pro captures if I am too close for the 300+1.4
I wonder if Sony will produce an OM-1 type camera and lens to compete. Clearly the OM-1 wins on this comparison ! Interesting Dennis keep up the good work 👍
Thanks Mark :) you know i love the A1 and GM600 .. but this has its place in my bag for sure! but for "i absolutly dont wanna miss this shoot" situations i grab the A1 until OMs AF get a little more reliable in difficult situations :) i can be done with the OM-1 but when i also got the A1 in my bag i go for that in these situations
The 150-400mm lens is a lot more expensive so you would hope it's really sharp. I shoot my 200-600mm at F7.1 most of the time, but if you shoot at F8 it becomes razor sharp and I feed it would compare to the 150-400mm. Just the way it goes with cheaper lenses they are never razor sharp wide open, but it is still sharp enough at F6.3 for me.
I agree with you and think the 200-600 is fantastic and more than enough for many photographers :) i just like the OM set better and had the opportunity to get it and that works for me (and still have the A1+GM600mm) :) so i think my bases are well covered for now .. haha ;)
Hi there, a very interesting comparison indeed! Liked and subscribed. So far, I shoot Olympus/OM System only and have an OM-1 too. Well two of them, if you also count the classical 1972 film SLR. I know, you did not want it scientific, compare rather from a practical standpoint and did very well with that. But I still wonder how fair that is. For a real equivalence between the sensor sizes in regards of image composition, the Sony would have needed an 800mm lens to have the same field of view as the 400mm. To then have the same depth of field, you would need to stop it down but you would keep the shutter speed the same, to freeze the action the same amount. To have the same exposure, you would need to raise the ISO on the Sony accordingly. OTOH you were more into comparing the image quality of the lenses and the overall system on a practical level. For a lens comparison, keeping the settings mostly the same makes absolute sense for me. Also the 50mp of the A1 can be cropped by factor 2.5 before even reaching the 20mp resolution of the OM-1, so cropping it more like you obviously did is not at all unfair either. The depth of field difference did not matter much in your specific application of shooting birds flying far away. The resulting images speak for themselves and the difference in rendering quality is truly astounding. I do not that much shoot wildlife and birds, so I can’t really justify yet buying me this lens, but it is a true marvel, well worth its price. Sorry for the very long and hopefully not too boring technical rant, LOL. I love pondering equivalence questions, they taught me a lot about the technical aspects of photography and always brought me to the conclusion, that I am very well served with just staying with my system of choice.
Useful and interesting clip. I already had the OM System 150-400mm lens and OM-1 camera and now also have a used but in excellent condition Sony a1. The also used Sony lens I opted for is the 100-400mm rather than the 200-600mm. More compact and versatile which when linked with the x1.4 TC results in 560mm given the higher f stop. I still have to get use to using the Sony a1 which will take time but the combination I have should enable me to potentially obtain reasonable action shots in frame with the ability to crop and keep details due to the 50 mega pixels. Will be interesting to see how the Sony does with video 🧐😊😊
It was quite difficult to evaluate the sharpness in these paired photos. What happens if you look at 1:1? I find that looking at pixel resolution, the Olympus 300 F4 is pin-sharp while the 100-400mm reveals its limitations. And would it be possible to give each pair of images a little longer on the screen?
I will say if i should pick a camera the A1 would be the choice but if the pick was the sets here i would go with the OM gear because of the fantastic M.Zuiko 150-400 with build in TC 👍🏻👍🏻👍🏻
Interesting comparison. I shoot Sony so I'm familiar with that platform. Occasionally I'll think about buying into the OM system. The photos from the OM-1 are the best I've seen. The photos from the Sony, though, aren't the best I've seen. Any idea why? The OM seems to beat the Sony in this comparison.
Thanks 😀 there are no doubt the A1 is much better than OM-1 but the OM-1 delivers top perfomance in photos, video AF is not that impressive 🤨 maby its the post work that makes a difference? i do need to work more with the OM-1 files but it can be done 👍🏻😀
Hey Dennis. You perform some of the best comparisons (if not the best)... Real world use and comments from practice... It would be great if you could do a comparison between A7iv+200-600 and OM-1+100-400... (if possible?) This is the equipment price-point for the vast majority of ''mere mortals'' photographer's budget, and would be really interesting to see comparison at the equivalent FL and A7iv at 600 cropped to ''eq 800mm'' (wide open and stopped down a stop), and AF consistency... Keep it on, fresh and different from the bulk 🙂 best regards
Thank you Sash 😁 appreciate your nice comment. I dont have access to any other gear ATM but if i get the chance i will try out some more combinations 😁
Thank Dennis for the comparison, great to hear from a pure wildlife user, how is the AF of the OM vs. the A1? that is key for BIF for me and other wildlife shooters i am sure, thanks buddy
Thank you Quan 👍🏻😁😁 Its good on the OM-1 but not A1 good in my opinion BUT ... it is good, especially in photo mode with bird recon. ON its really good .. but in difficult conditions like ripples and waves in water, dirt fields, vegetation in the background etc. i can fall of the target or miss it more than A1. Video AF is not easy to work with but im starting to learn to use it. Im working on some new videos where i have used the set "for real" 😁😁😁 hope to have them ready in a week or two.
Interesting comparison Dennis, thanks for taking the time to do it. I was surprised how well the IQ stood up to the test. How do you feel about the AV v OM in terms of menus and ergonomics, along with customising the buttons for bird photography. Many Thanks
Thank you 😁 both are easy to configure to your likings but im so use to the A1 that i still would choose it but maybe that changes when i have been using the OM-1 for a longer time 😁
I heard that Sony 200-600mm @600mm is MUCH sharper closed down to f8. Also I assume that you cropped the Sony shots more heavily. Of course that is your workflow, still I think that you could have squeezed more of Sony setup.
The first you notice are the A1 files and be MEGA cropped :) but i must say i am positively surpriced of how good the files look from the OM-1 with the 150-400 infront. Also i have played around with upscaling in Topaz photo AI and that works really well!
@@DennisJacobsenWildlife That's good info! I shoot a Canon R5 with the 100-500 f7.1 which becomes 420-700 f10 with the 1.4tel and have been really considering moving to the OM-1 with the 150-400 because of the high ISO I always end up shooting in anything less than great light. These examples of the A1 & 200-600 are very similar to my situation so really appreciate the real world comparison. Thanks for sharing!
I was set on buying an A7 IV and 200-600 until I watched this just now....thanks...I've been trying to pick my next system for a month now and I was sure I wanted the Sony. Now I'm not. The 150-400 is so much faster than the Sony 200-600 that it looks like it negates the better low-light performance of the A1. But I wonder would it still manage to stay with the Sony when shooting birds inside a forest, in the shade? Edit: I just checked the price on the OM 150-400....I'll pass. :D
@@DennisJacobsenWildlife After finally nailing some tack sharp and detailed photos today, using my 7d2 and Sigma 150-600 Contemporary lens, I might give this combo one more chance before I move on. It's forcing me to position myself so I can make most of the light in order to get such a shot and I believe that's going to be invaluable going forward, regardless of how modern and expensive gear I get. Still not happy with the quality and details of my bird in flight photography but it may be me and not the camera. It feels like the af, even though locked and confirmed isn't always as precise as it should be. I'll try the Sigma with the stabilisation off at such high speeds (1/1600 to 1/2500) as I don't think it helps at all, maybe quite the opposite.
Thanks for this comparison! It proves one thing : the OM is a better glass (also more expensive)It would be interesting to compare the 600 GM swell with the OM: then you compare the 2 toplenses of both systems.
Yes. A camera system is a system and ideally you would chose the best system for the job. And yet we may take personal preference into account, haptics, ease of use, cost.
I think the contrast is better on the OM System, blacks looking particularly nice, hardly surprising with the glass costing what it does. But I would imagine some light editing with the Sony files would bring it into line with the OM, not drastic differences, but noticeable for sure
Jeg har det objektiv og er virkelig tilfreds med det sammen med mit Sony A9, men vægten på Sony objektivet kan sommetider være en udfordring efter længere tids brug, da jeg har en dårlig ryg. Selvfølgelig endnu et like herfra
hi Dennis the OM combination is the best in this comparison. I am very curious how the developments at OM systems will look like. they have big delivery problems with 150-400mm lens. I wouldn't be surprised if the Japanese investment company Jip, which owns Om-systems, resells everything to a third party. we will see for ourselves in the near future. Thank you for this beautiful and informative video.👍
The only delivery 'problems' OM have is they can't build the lenses fast enough to cope with the demand. That's a nice problem to have from OM's perspective.
@@MotoRich900 worldwide, this lens is nowhere to be found, while the chip shortage has now practically been solved, so I think something else is going on.
Im am comparing the best two zoom lenses in that range from the two brands :) both well known options for wildlife 🙂 i also compared the Olympus 150-600 f/4.5 to the Sony 600mm f/4 i think it is interesting to results compared on the setups i see out in the field .. but in the end, whats make you happy is what you shoot with!
don't forget, that the body price difference is quite similar, but in other direction (A1 vs OM1 is now - 7300€ vs. 2000€), so the set price is a similar.
Your are comparing a OM pro lens with a SONY standard lens, not even a GM lens. So what's the sense behind that? The IQ is about 90% about the lens and not the camera, so you are comparing high-end with a budget version G lens, it's was clear who should win before you even started. In addition the 200-600 G has a high variance in IQ, we are using two of them and use the sharper for pics and the less sharp one for videos. That's definitely not the case with the OM Pro lenses as well as not with a 600 F4 GM, which we also own and use as our main wildlife lens attached to our A1's ......

Thank for commenting Rob :)

Thank you Dennis for taking the time to do this comparison!. I will never own the 150-400, but my 300f4 is a super lens too on the OM-1.
Thanks Robert 😁 i think they are close in performance as i can read on forums etc.
Fairly clear outcomes.
:) yes
I have the Same opinion! The OM System SET is the better choice for many reasons. Other Wildlife Photographers, like Mike Lane and Daniel J Cox have the same opinion and also chose the OM set. They made very interesting videos about that. Thank you to bring this out. It can help many people to choose better!
Thank you for sharing :)

Thank you Dennis for a fair and down-to-basics comparison video. The Olympus 150-400 is a fine lens with a complex design. Interesting you mention it is well balanced, i.e. does not feel front-heavy. I only regret hesitating before acquiring the lens, already in possession of the great 300/F4. Acquiring the OM-1 as an upgrade over from the E-M1.2/E-M1X was a no-brainer in comparison.
Thank you Tord :) appreciate your input!
Wonderful comparison and I use OM systems mostly. Thanks.
Thank you :)
thanks for the lovely shots and the nice comparison. i am olympus user since 2004 in the digital era, was so happy never thought i had a problem until they started to hear about the superiority of FF, got the Nikon D810 (acutely it was a gift form my uncle) yes got many stunning results, just as i get form my olympus e5 + Sigma 50-500 mm, but both were too heavy to handhold. in the mirrorless world and when the Zuiko 300 mm f4 came the battle was over, and the D810 + Nikkor 100-500 mm became history.
You are welcome and thank you for sharing your storie :) appreciated
I use to use Canon gear. In 2019, when I got back into photography I bought into the mft (micro 4/3) system as it was finally at the point where it was good enough for my needs and still using that system. Before getting the OM-1, I looked and Canon, SONY. I was not interested in full frame bodies. The OM-1 is a great camera and the price is still reasonable. I have recently purchases the Olympus 150-400mm (stick in major sticker shock). Very impressed with the lens and looking forward to making great images with it over the years.
Thanks for your comment and i agree with you, the MFT makes great photos and videos :)
very expensive lens i could not offer it tell now and i feel sorry to spend more in om1 come the final image is not that quality
Very interesting comparrison Dennis.
Thanks Roger :) appreciated!
Geez that is very interesting. Very good information
Thank you for commenting! :)
Amazing comparison work, thank you so much
Thank you :) glad you think its usable
Great comparison, I have the OM-1 but sadly I can't afford the 150 to 400. I do have the 100 to 400 leica which for it's price and waite is still a good combination.
If I got an OM-1, one of the Leica/Olympus 100-400s, or 300f4 would be my only options for long lenses. Glad to hear you enjoy the 100-400 on the OM1!
Thanks your comment :)
Its a really good lens! love using it :)
Nice video. Thank you.
Your comments reminds and reinforce why in 2007 when my film camera gave up the ghost and I moved to digital why I decided against full frame and went with Olympus. Lenses are more important then camera and Olympus make some of the very best and have done for the last fifty years.
Ultimately the picture quality will be better with full frame but to properly exploit the full frame sensor one has to use their pro lenses and when you are talking about photographing wildlife that usually means fast long primes and zooms and the costs of these are very expensive. The Olympus pro lenses and back then the semi pro line were the deciding factor for myself because they were the equal or better then practically anything full frame could offer at the same focal lengths and they were much cheaper.
With the arrival of the OM-1 there is a body which can exploit them and provide a genuine alternative to the more expensive full frame offering from Canon, Nikon and Sony, particularly when paired with a lens like the 150-400, which is genuinely revolutionary, for less then £10,000.00 Sterling.
A comparable Full frame system would cost around £30,000.00 Sterling. Yes, it would perform in ultimate terms better then the OM system but in the majority of cases one would not notice the difference in picture quality and the OM system would be considerably cheaper, lighter and more versatile.
If however, you know that most of your photography is going to be taken at high iso (3200) and above and you have very deep pockets and you are willing to carry heavy fast lenses around and mostly work with a tripod and a heavy monopod and gimbal, by all means stick with full frame. For the rest of us, give the system a try using the try before you buy loan scheme. I suspect you will be pleasantly surprised, particularly if you keep the subject large in the frame so you don’t have to crop excessively, exploit the image stabilisation and keep the iso as close to the base setting of 200 as you can, set up the exposure blinker alerts and focus peaking and bird or animal detection and exposure as far to the right as you can before the blinker’s indicates you are clipping the highlights. In post you can recover 3 stops of over and under exposure if you make a mess of things in camera.
Most of all, have fun.
Thank you Steven for your opinion and and comment :)
@@DennisJacobsenWildlife that’s just it, ….an opinion wrapped in a series of constraints and the conclusion can only be that you use what’s best the task in hand within the budget available and your videos emphasise the point that’s it’s a personal choice. Well done.
Now on my last day of a 4 week bicycle tour with the OM1 (40-150 2.8 pro, 100-400 and mc14), I shot 55000 pictures, got amazing shots of Kingfishers, Sea Eagles, Ospreys, Purper Herons, Sterns, Little Egrits, etc in sometimes harsh weather conditions (tropical heat, heavy rain and summer storm Poly). The OM-system is great for such conditions having the camera on a sling while cycling to be ready for every opportunity. Also used it on water splashing canoe trips several times. Love the system...
Thanks for sharing 🙏🏻😀📷
I like my 100-400mm lens
Thanks for making this video. I have been tempted to buy the om1 and 150-400, this video really helps. I tried the 150-400 at a show it felt so light I thought it wasn't real, but it was.
Its a great set! just remember its not in the league of the newer FF mirrorless systems in IQ .. BUT it does make some great photos and videos i my opinion :)
@@DennisJacobsenWildlife I have A1+200-600 and also R7+100-400is ii. The R7 has some of the features the OM-1 has but they don't work well due to the rolling shutter. I pray A1 will add procapture but I fear my prayers will go unanswered.
@@daviddouglasuk I to think nothing more come to the A1 :/ I sold all my Sony gear adn go with OM system this year and see what happens next in the marked! :) im interested to see what the Canon R1 will deliver when its released.
For me, the Pro Capture technology in the OM-1 is a huge advantage for bird photography.
It is a great feature! i dont understand why other brands haven't done this long ago 😀
Pro capture with the SH drive modes and the huge 200 shot buffer on the om1 ii is insane
Thanks for the comparison. It shows how important good glass is. I am surprised by the difference. I am happy invested in the 150-400 🙂.
It was fun making it :) thank you for your comment!
Thanks for this video and confirming I made the right decision in purchasing the OM1 and MZuiko 150-400 pro lens. And trust me, if could afford it and have the stamina to carry the a1 and the 600mm, I would have gone in that direction. In the back of my mind, I had a gut feeling that in purchasing the A1 with the Sony 200-600mm, I would have missed out on the picture quality vs the OM1 and the MZuiko lens for photos. I don't shoot video as much. So, thanks, you have confirmed that image quality comes from what type of glass you put in front of the camera and not as much as the number of pixels. Also, I can confirm that the om1 can shoot in super low light with iso of 6400 and 10,000 in a pounding rain and produce quality images after post processing.
You are welcome :) i also have the Sony GM600 and with the A1 its crazy fast and precise but that said the OM system delivers amazing result too :)
Really nice video, it would be very interesting to se a comparison with the Sony 600 f4 if the A1 would get the upper hand then.
All ready did in a previous video ;) its in my video list on the channel
Ohh, didn't know that, or I've forgotten 😆
On my opinion both systems are great. For wildlife an Macro I would prefer the OM. For sports and daily purpose the A1 is IMHO the better option. There is no perfect system for all situation. If you do a lot of cropping - the megapixels of the A1 are great. If you would like good results OOC then the OM setup will satisfy you. Another thing is size an weight. This is the habitat of OM. Best thing you can do is: go to your local camera store, lend out the system you prefer and try it out yourselve, before you buy it. I have Sony AND Olympus and this combination is perfect for me.
Agree with you here and also the reason i keep both systems! :) thanks for commenting, appreciated!
Great video comparison - shows OM-1 really punches above its weight class. I shot last year's COTA F1 and this year's COTA MotoGP with OM-1 and 150-400. My friend uses A1, although with 100-400 and not 200-600, and we both agree that the OM-1 pictures compared very well with the A1 - particularly in sharpness. I did end up selling the 150-400. Great lens, but I don't shoot sports and wildlife often enough to justify. Same justification that kept me from buying an A1. Beast of a camera, but after using the OM-1, I am more than satisfied with image quality and AF performance.
Thank you for your input E 😀 appreciated!
My first though was how well the 200-600 did compared to a 4x more expensive lens of the OM. A little sharpening on the 200-600 images and they are quite similar.
Actually the A1 has 50mp vs the OM-1s 20MP. Taking into account the focal length differences, the OM-1 only has 35MP at 600mm, and it's noticeably out resolving the Sony setup.
Or how well a £1659 OM-1 did compared to a £5879 A1!
@@stevemurnan1702 What?, The sensor on the A1 can not replicate sharpness & details that isn't there -aka fed by the lens. There is a konsensus that lenses are the key for catching sharp and detailed images. Lesser quality lens on the OM body would have shown the real differense between a pro and non pro lens. Here is a budget lens compared to a pro lens and it keeps up quite well imo. If bodies were tested surely the A1 Should had carried the 400mm f/2.8 GM og 600mm f/4.0 then there's another story.
@@arildhagen3820 agreed on your point to a degree but for wildlife photography, for proper composition it would be a huge advantage to shoot with a pro zoom lens than a fixed one. I don’t know this but does Sony have a pro zoom available? And if Sony ever come up with a 200-600 pro lens I would bet than many would trade in their 600mm.
@@joeret2896 yes, the 100-400 GM is a pro lens. They also have som normal range zoom but are missing some in the longer range where they only have primes
Interesting video and great to see the OM-1 can hold its own against such highly regarded full-frame company.
It is for sure a good camera! 😁
FACE OFF time!
I came from 200-600 A7rIVa and have the same findings.
Everyone is in different stages of their photography journey, I outgrew the 200-600 very quickly, which makes the pricing irrelevant when you need to upgrade after only 6 months.
I then learnt not to go for the next logical upgrade step, but to skip 2 steps (if you know what I mean) so you can grow and develop into it. But at the top end of town, the law of diminishing returns is very painful on the wallet.
I know many starting with the 200-600 and soon after upgrading. This ofcource are if you are in a position to spend this kind of money on gear.
The Sony kit is a great kit but it appears the OM seemed to kick it's butt. I know end result is going to favor the Sony kit for greater ability in the A1 and A2 area. But the OM is definitely more portable . That Zuiko lense is outstanding. Thanks.
Thanks Thomas 😁 nu daubt the A1 is superior but the MFT system delivers some great results! the reason i went MFT was the M.Zuiko 150-400mm lens 🙂
Thanks for the comparison .
You are welcome and i had fun doing it :)
I have the A1 with the 600GM and the OM-1 with the 300Pro. The Sony 600 and the Olympus 300 are both fantastic lenses. The Sony takes a 2x particularly well but the Olympus is surprisingly good too with the 2x. Bird eye tracking is good on both, but general subject tracking on the OM-1 is two generations behind. It is definitely easier to go out with the Olympus. The 600GM is a better lens than the Sony zoom as one would expect. It is the best 600f4 I have ever used. Olympus desperately needs better general tracking and a few more pixels would be nice.
I'd agree with you on the OM-1general subject tracking. That's the weak spot but specific subject tracking (bird, animal etc) are pretty good and not much different from my R5.
Absolutely agree here! thanks Don :)
I’d love to get another one of these comparing an a7iv with the 200-600 vs the om-1 with the 100-400 as the cost for each pair is much less at circa 3k
If i get the chance, maybe 😃
Thanks for the comparison. I have used the 200-600mm for a long time, and I find it significantly sharper at F8. I only use F6.3 when im challenged by the light. In good light - always F8.
I think cost over performance you get a lot in the OM system. Im a Sony user, but think I will look more into the OM system.
Thanks for your comment Jon. The OM system gear are super good .. and if they can tweak the AF to be a little more consistent in BIF/Action it will be super nice
You can achieve almost the same results if you apply appropriate sharpening to the raw files in post-processing, and the Sony also has less noise. Considering the price (4x lower then 150-400mm) the 200-600mm is an amazingly good lens and a great value.
Thanks for doing this comparison. You make it harder for me to resist from getting Oly 150-400mm F4.5 lens :-). This is somewhat to be expected even though I have seen some people kept arguing the other way. OM-1 package would cost more though. But I agree, I would go for the OM-1 package.
Thanks Narin :) appreciate you input here.
Thanks for the comparison. I would be interested in comparing the Olympus 150-400 vs the Sony 100-400. I love the A1 (although an update is needed) but the Olympus 150-400 is obviously a fantastic lens and clearly sharper than the Sony 200-600. But for 3.75 times the price it better be.
Thanks RM Clark :) i have the the 100-400 and its a great lens but for small birds on larger distances the Olympus 150-400 is better but also more expensive! :)
The 300F4 is even (slightly) sharper but without the flexibility of a zoom but at a fraction of the price. Also, the 300 with the 1.4 is my perfect combo for BIF. I carry a second body with the Leica 50-200 for closer shots or pro captures if I am too close for the 300+1.4
I wonder if Sony will produce an OM-1 type camera and lens to compete. Clearly the OM-1 wins on this comparison ! Interesting Dennis keep up the good work 👍
Thanks Mark :) you know i love the A1 and GM600 .. but this has its place in my bag for sure! but for "i absolutly dont wanna miss this shoot" situations i grab the A1 until OMs AF get a little more reliable in difficult situations :) i can be done with the OM-1 but when i also got the A1 in my bag i go for that in these situations
I wish Olympus make OM-1 mark II, with more megapixels (like.. 30+?), and make a 300 mm f2.8 Pro lens. That would sick. I can't even imagine.
Could be cool! :)
The 150-400mm lens is a lot more expensive so you would hope it's really sharp. I shoot my 200-600mm at F7.1 most of the time, but if you shoot at F8 it becomes razor sharp and I feed it would compare to the 150-400mm. Just the way it goes with cheaper lenses they are never razor sharp wide open, but it is still sharp enough at F6.3 for me.
I agree with you and think the 200-600 is fantastic and more than enough for many photographers :) i just like the OM set better and had the opportunity to get it and that works for me (and still have the A1+GM600mm) :) so i think my bases are well covered for now .. haha ;)
Hi there, a very interesting comparison indeed! Liked and subscribed. So far, I shoot Olympus/OM System only and have an OM-1 too. Well two of them, if you also count the classical 1972 film SLR. I know, you did not want it scientific, compare rather from a practical standpoint and did very well with that. But I still wonder how fair that is. For a real equivalence between the sensor sizes in regards of image composition, the Sony would have needed an 800mm lens to have the same field of view as the 400mm. To then have the same depth of field, you would need to stop it down but you would keep the shutter speed the same, to freeze the action the same amount. To have the same exposure, you would need to raise the ISO on the Sony accordingly.
OTOH you were more into comparing the image quality of the lenses and the overall system on a practical level. For a lens comparison, keeping the settings mostly the same makes absolute sense for me. Also the 50mp of the A1 can be cropped by factor 2.5 before even reaching the 20mp resolution of the OM-1, so cropping it more like you obviously did is not at all unfair either. The depth of field difference did not matter much in your specific application of shooting birds flying far away. The resulting images speak for themselves and the difference in rendering quality is truly astounding. I do not that much shoot wildlife and birds, so I can’t really justify yet buying me this lens, but it is a true marvel, well worth its price.
Sorry for the very long and hopefully not too boring technical rant, LOL. I love pondering equivalence questions, they taught me a lot about the technical aspects of photography and always brought me to the conclusion, that I am very well served with just staying with my system of choice.
Thank you for your thoughts on the two systems and i really appreciate you and others take the time to see the content and share comments here 😀
Useful and interesting clip. I already had the OM System 150-400mm lens and OM-1 camera and now also have a used but in excellent condition Sony a1. The also used Sony lens I opted for is the 100-400mm rather than the 200-600mm. More compact and versatile which when linked with the x1.4 TC results in 560mm given the higher f stop. I still have to get use to using the Sony a1 which will take time but the combination I have should enable me to potentially obtain reasonable action shots in frame with the ability to crop and keep details due to the 50 mega pixels. Will be interesting to see how the Sony does with video 🧐😊😊
I think you are gonna be happy with the video on the A1 :) thank you for your comment!
It was quite difficult to evaluate the sharpness in these paired photos. What happens if you look at 1:1? I find that looking at pixel resolution, the Olympus 300 F4 is pin-sharp while the 100-400mm reveals its limitations. And would it be possible to give each pair of images a little longer on the screen?
Thanks for your commend 😀 i will take it with me for next time i make a camparison like this 😀
The Olympus appears to be superior and you can't deny the handling is superior as well. Hard choice
I will say if i should pick a camera the A1 would be the choice but if the pick was the sets here i would go with the OM gear because of the fantastic M.Zuiko 150-400 with build in TC 👍🏻👍🏻👍🏻
Hello, was somehow clear! Maybe there will be a firmware update at some point or an OMII.
I do hope for some AF improvents in the future .. but lets see what happens :)
Interesting comparison. I shoot Sony so I'm familiar with that platform. Occasionally I'll think about buying into the OM system. The photos from the OM-1 are the best I've seen. The photos from the Sony, though, aren't the best I've seen. Any idea why? The OM seems to beat the Sony in this comparison.
Thanks 😀 there are no doubt the A1 is much better than OM-1 but the OM-1 delivers top perfomance in photos, video AF is not that impressive 🤨 maby its the post work that makes a difference? i do need to work more with the OM-1 files but it can be done 👍🏻😀
Hey Dennis. You perform some of the best comparisons (if not the best)... Real world use and comments from practice...
It would be great if you could do a comparison between A7iv+200-600 and OM-1+100-400... (if possible?)
This is the equipment price-point for the vast majority of ''mere mortals'' photographer's budget, and would be really interesting to see comparison at the equivalent FL and A7iv at 600 cropped to ''eq 800mm'' (wide open and stopped down a stop), and AF consistency...
Keep it on, fresh and different from the bulk 🙂
best regards
Thank you Sash 😁 appreciate your nice comment. I dont have access to any other gear ATM but if i get the chance i will try out some more combinations 😁
Thank Dennis for the comparison, great to hear from a pure wildlife user, how is the AF of the OM vs. the A1? that is key for BIF for me and other wildlife shooters i am sure, thanks buddy
Thank you Quan 👍🏻😁😁 Its good on the OM-1 but not A1 good in my opinion BUT ... it is good, especially in photo mode with bird recon. ON its really good .. but in difficult conditions like ripples and waves in water, dirt fields, vegetation in the background etc. i can fall of the target or miss it more than A1. Video AF is not easy to work with but im starting to learn to use it. Im working on some new videos where i have used the set "for real" 😁😁😁 hope to have them ready in a week or two.
Interesting comparison Dennis, thanks for taking the time to do it. I was surprised how well the IQ stood up to the test. How do you feel about the AV v OM in terms of menus and ergonomics, along with customising the buttons for bird photography. Many Thanks
Thank you 😁 both are easy to configure to your likings but im so use to the A1 that i still would choose it but maybe that changes when i have been using the OM-1 for a longer time 😁
En mycket bra test! tack
Tak Jimmy :) i just compare like i shoot and this is the result
I heard that Sony 200-600mm @600mm is MUCH sharper closed down to f8. Also I assume that you cropped the Sony shots more heavily. Of course that is your workflow, still I think that you could have squeezed more of Sony setup.
Thank for your input Pawel :)
Very interesting comparison Dennis. Do you find much difference when editing the files from the two cameras?
The first you notice are the A1 files and be MEGA cropped :) but i must say i am positively surpriced of how good the files look from the OM-1 with the 150-400 infront. Also i have played around with upscaling in Topaz photo AI and that works really well!
@@DennisJacobsenWildlife That's good info! I shoot a Canon R5 with the 100-500 f7.1 which becomes 420-700 f10 with the 1.4tel and have been really considering moving to the OM-1 with the 150-400 because of the high ISO I always end up shooting in anything less than great light. These examples of the A1 & 200-600 are very similar to my situation so really appreciate the real world comparison. Thanks for sharing!
Does the OM-1 have bird eye detection?
Yes is does, works great 👍🏻📷
How were the shots processed? Capture One? What sharpening diameter and level?
Same default settings i Capture one, just corrected the white balance to match them up :)
Great video. Really interesting seeing the OM1 150-400 in use. The system doesn’t get marketed properly.
Have you updated the OM1 for the autofocus?
Thanks :) yes im on the newest firmware on the OM-1 and there are still room for improvement! especially for video with long glass like the 150-400
Damn are these RAW files? Feels bad for people who needs photography validation off of Sony's price tag.
Yes all shoot in RAW and just outputted with default setting in Capture One to jpg 👍🏻
I was set on buying an A7 IV and 200-600 until I watched this just now....thanks...I've been trying to pick my next system for a month now and I was sure I wanted the Sony. Now I'm not. The 150-400 is so much faster than the Sony 200-600 that it looks like it negates the better low-light performance of the A1. But I wonder would it still manage to stay with the Sony when shooting birds inside a forest, in the shade?
Edit: I just checked the price on the OM 150-400....I'll pass. :D
Hehe yes it is an expensive lens! You wont go wrong with the Sony set, it is really good and alot of people uses it with super results!
@@DennisJacobsenWildlife After finally nailing some tack sharp and detailed photos today, using my 7d2 and Sigma 150-600 Contemporary lens, I might give this combo one more chance before I move on. It's forcing me to position myself so I can make most of the light in order to get such a shot and I believe that's going to be invaluable going forward, regardless of how modern and expensive gear I get. Still not happy with the quality and details of my bird in flight photography but it may be me and not the camera. It feels like the af, even though locked and confirmed isn't always as precise as it should be. I'll try the Sigma with the stabilisation off at such high speeds (1/1600 to 1/2500) as I don't think it helps at all, maybe quite the opposite.
Thanks for this comparison! It proves one thing : the OM is a better glass (also more expensive)It would be interesting to compare the 600 GM swell with the OM: then you compare the 2 toplenses of both systems.
Thanks :) thank you for your comment and looke some episodes back .. i already did :)
Yes. A camera system is a system and ideally you would chose the best system for the job. And yet we may take personal preference into account, haptics, ease of use, cost.
Agree and thanks for your comment :)
Better glass always beat better camera.
Agree :)
I think the contrast is better on the OM System, blacks looking particularly nice, hardly surprising with the glass costing what it does. But I would imagine some light editing with the Sony files would bring it into line with the OM, not drastic differences, but noticeable for sure
Thanks Roger! :) appreciated!
Jeg har det objektiv og er virkelig tilfreds med det sammen med mit Sony A9, men vægten på Sony objektivet kan sommetider være en udfordring efter længere tids brug, da jeg har en dårlig ryg. Selvfølgelig endnu et like herfra
Begge systemer er gode men ja det er fedt OM er mindre og vejer mindre!
not fair comparison, $1750 vs $7000+ isn't?
Yeah not fair at all. Not only is the A1 $7000+, the sensor is way bigger.
@@HokKan prices comparable you have to use both lens and body together
Set prices are around the same here :)
Thank you for your opinion :)
Exactly :)
hi Dennis
the OM combination is the best in this comparison. I am very curious how the developments at OM systems will look like. they have big delivery problems with 150-400mm lens. I wouldn't be surprised if the Japanese investment company Jip, which owns Om-systems, resells everything to a third party. we will see for ourselves in the near future. Thank you for this beautiful and informative video.👍
The only delivery 'problems' OM have is they can't build the lenses fast enough to cope with the demand. That's a nice problem to have from OM's perspective.
The delivery issue was due to the global chip shortages.
@@MotoRich900 worldwide, this lens is nowhere to be found, while the chip shortage has now practically been solved, so I think something else is going on.
No, it's the capacity of the lens manufacturer. OMD\Olympus didn't expect the large number of orders that the lens has accrued.
Thank for your comment! :)
You are comparing Olympus pro lens to Sony consumer lens.Pro lens against pro lens is way to go
Im am comparing the best two zoom lenses in that range from the two brands :) both well known options for wildlife 🙂 i also compared the Olympus 150-600 f/4.5 to the Sony 600mm f/4 i think it is interesting to results compared on the setups i see out in the field .. but in the end, whats make you happy is what you shoot with!
Wow, a €2000 lens against a €7500 lens. What do you expect?
Thank you for your opinion Wally :)
don't forget, that the body price difference is quite similar, but in other direction (A1 vs OM1 is now - 7300€ vs. 2000€), so the set price is a similar.
Your are comparing a OM pro lens with a SONY standard lens, not even a GM lens. So what's the sense behind that? The IQ is about 90% about the lens and not the camera, so you are comparing high-end with a budget version G lens, it's was clear who should win before you even started. In addition the 200-600 G has a high variance in IQ, we are using two of them and use the sharper for pics and the less sharp one for videos. That's definitely not the case with the OM Pro lenses as well as not with a 600 F4 GM, which we also own and use as our main wildlife lens attached to our A1's ......
I compared them for versatility and size 👍🏻📷 i also had the A1, GM600, 200-600, 100-400 so used them all 🙂 thanks for your input 🙏🏻
OM System will become crashed next year. There was a reason that Olympus had sold their photo part.
I hope you are wrong becuse the OM-1 + 150-400 kicks ass and hope they will keep develop better and better 4/3 cameras :)
