In this short episode i am showing some examples on the AF on OM-1 and Olympus M.Zuiko 150-400mm f/4.5 and how it performs on photographing birds in flight (BIF)
I always love your frank and honest findings, it is what it is right? I too wish they can be better AF -C soon, then i will go back to M43rd,TFS, Good going my friend.CHEERS!!!!!
Thanks for showing your OM-1 bird-in-flight results. After a 40+ year career of using FF gear for newspaper work (and rehab from repetitive stress injuries from carrying all that gear) I found the siren call of portability hard to resist, trying my hand at bird photography in retirement with the Lumix G9. While MFT is not likely to ever replace top-of-the-line full frame gear I have found there are plenty of AF adjustments in the G9 menu that have improved my keeper rate even for birds like black skimmers coming straight towards me. Lumix has been great about software upgrades. OM Systems would be smart to work with someone of your experience to improve their product. Thanks for giving MFT a try.
I agree that the focus does go in and out on occasion for me and OM needs to fix this, however I do get really good/great results with SH2(I select 100 fps) and I use “all focus points” for the focus area, AI bird detect and I have my tracking sensitivity set to -1. The speed is so fast that even with some occasional soft shots, I often have way too many keepers to sort through. It’s not the perfect system(no system is) but I always try to remind myself that pros were taking phenomenal photos of BIF long before this technology came about. Thus, while issues are there, I try to remember to appreciate the technological advances that we do have and just go out and enjoy the camera:) I’m glad you’re enjoying the OM System setup
Thoughts from an mainly Olympus user. I have only had Olympus camera's capable of photographing birds. I never had the possibility to compare with the AF from other systems in the long term. The only thing I know is that my bird photography is improved significantly with the OM-1 and 150-400mm, also over the E-M-1x and E-M1 III. The most important thing is that I still enjoy photography with it. Because of the price, weight and size benefits. As I cannot afford any high end full frame 400mm lenses and high end full frame camera's that could benefit from it.
You can get a Nikon Z8 and the 400 f4.5 for a similar if not lower price than your current setup. You'll get a significantly better image in terms of noise, DR, sharpness, carry a similar weight, but of course sacrifice on the flexibility of the zoom and the 800mm equivalent reach.
@@Wildridefilms I am using it on 1000mm a lot. Cropping won't close the gap. I never seen any comparisons between the two. Sharpness is already very good with the 150-400. I should have mentioned 800mm instead of 400mm. My bad.
I had the A1 and GM 600mm and thats crazy fast and precise but also very expencive and large/heavy 😀 but OM-1 and 150-400 are also very very good for sure 📷📷📷
I have the OM1 plus 40-150 f/2.8 and 300mm f/4 and 1.4x TC. I also have the Canon R5 plus 100-500 L series lens. I love both systems equally, I have not measured this scientifically, but my feeling is that for BIF I get a higher percentage of sharp images with the Canon, but despite that, the higher 50fps frame rate with the OM1 means that I'm getting slightly more sharp images using the OM1. At the moment I'm preferring the Olympus overall, because of the higher frame rate and lighter weight, and most importantly because of the PRO-Capture feature and for me, this is a game changer. If the R5 firmware was updated to include an equivalent pre-capture ability it would be tough to choose, but when you take price into consideration, the 150-400mm (I am waiting for one) is fantastic value for money, when compared with it's Full Frame equivalents. That value for money and the difference in portability suit my needs rather well, BUT I wouldn't want to lose access to the amazing image quality of my R5...for when portability is not an issue.
Interesting Dennis - and also surprising you have sold your Sony gear. I understand the size and weight challenge but its probably the best equipment you can buy. I have travelled with birders doing the A1/600 GM or A1/200-600 and I have been very impressed with the quality. I use the R5 with the 100-500 and now also an R7 (Crop) - very good quality (R7 not equal to the R5) but the price is also very low. Also travelled with OM Gear guys - seems very good but yes AF is not at the same level as the A1 or R5. Will be interesting to see where You go in terms of equipment - very good work Dennis. Hilsen Per
Hi Per, thanks for your input 😁 and yes the A1 was really really good for sure! but for now im happy with the OM system gear and its size! what happens next i dont know .. i hope to see the AF on the OM-1 improving and if that happens i may stay on this system for a while 😎
@@DennisJacobsenWildlife - I understand - thats why I stay with my R5/7 - the 100-500 only weighs 1300 g and I also took of the battery grip. Enjoy the OM System - I like the 4.5 capability
1000% agree!. It’s good and never will be perfect, but the camera deserves to be better than this. Shooting at 20, 25 or 50fps, hoping the perfect shot is the sharpest is not something i like to do.
I feel the same Robert! like i said i can shoot some GREAT BIF photos but you can not pick and choose what you want, but can only pick out a few really sharp ones here and there. Like i say in the video this only applies to BIF in all other situations i have no problems getting a great photos every time :)
Did you tried with less focus points? By example a zone of 25% from the sensor. I know it's more confortable with all focus points activated, but would be interesting to see if less focus points makes the system more precise.
What is your IS set to? For birds in flight I was having the same result when I used S-IS 1 but when I switched to S-IS 2 it got a lot better, I really love the OM-1 and 150-400 but I kind of think if we try and sell it I think we'd have a hard time as most people buy Nikon or Canon or even Sony. But what I am doing is just be a dual system shooter Canon Om system.
I understand your frustration Dennis. I do find that when tracking a bird in flight, I do get a few frames unsharp. It will even do it on a sequence of a bird that is fairly static. I recently shot a burst of pictures of Cuckoo`s mating. I too a burst of 40+ images, and even then it lost the focus on a couple of frames. Its then pulls back and they are pin sharp. As you say, its its a one of shot, and you dont nail it, its annoying.
Thanks for commenting Roger :) i do hope they keep improving the AF on the OM-1! i love shooting with this set and if they can tune in the AF a little better i will def. stay on this system!
This exactly matches my own experience though I have not tested my OM-1 so extensively, but I would not expect to need to. It's still a great camera and system for other subjects, but because of the poor subject tracking it offers little over the E-M1 mk3.
One Question: What firmware version did you install during the test? Because I have installed version 1.5 and I set the autofocus management to the best from settings menu, and I wouldn't have such significant evidence on moving shots (in my opinion),
I too have this inconsistency with BIF, it’s my biggest annoyance with the system. I keep hoping a firmware update will address this as it is obviously capable.
Hope OMDS will look at this and resolve the issue soon. I don't have this kind of inconsistency even when shooting with SH2. Yes, I do get soft images out of the series but nothing like yours. I never get 100% rate but it never goes below 85% for burst of 4 seconds and above. I don't hold my shutter the whole time though during the shooting sequence. I would release it and acquire the focus roughly every 3-4 seconds. I mentioned in your earlier video that I get higher sharp image rate with normal e-shutter at 20FPS. I do own two OM-1 and both don't produce results like yours. I don't think it has to do with your technique or settings. I am using almost similar setup as yours; CAF, AF on, +2 Sensitivity, Auto IS prioritize FPS, Release priority on (which should be worse as it will fire regardless of focus acquisition), Bird AI. My focus box for BIF varies based on situation from All, to Large to my own custom 3x7 primarily for capturing bird flying across.
Very strange you get so good results and i cant with my OM-1 for birds in flight. I still nedd to try out the 20fps setting and see if that makes a diff. but then it isen`t blackout free and thats to bad :/ do you have an instagram or somewhere you put op your phots? mine are here: instagram.com/dennisjacobsenwildlife and almost all the recent photos are from the OM-1 and i do get some great results but i cant pick and choose in the burst i do when shooting .. i can only pick out some REALLY sharp one here and there.
@@DennisJacobsenWildlife I am not on Instagram and hardly post anything on FB. I will try to send you a set of sequences I took more recently. I usually don't save all of them. However, I have the more recent one that I have yet processed so haven't deleted most of them. We will figure out how I share those few burst sequences. One thing I notice is that the heat haze or background with huge contrast will significantly lower the hit rate. But the sequences you shows on your content should be at least 85% of tack sharp images.
@@DennisJacobsenWildlife I just grab screen shots of the sequences I took recently. I could send you via email or we can do video chat as well. This way I can share your my screen live since I have two more recent sequences that i haven't deleted most of images.
The cameras yes but i depends what you put in front of them 😀 i wasn't to happy with the Sony 200-600 for BIF .. close to medium range it is great but at longere range and when you have to crop i wasn't happy with the results .. but again i also depends what result you expect! i you want prime quality the only way to go is prime lenses 😀😀
The last speak i made the eye AF jumped on / of me many times and that was in a situation where it should be easy for the camera to stay on my eyes 😕 Really hope they can fix the AF because its a fantastic system 👍🏻
@@DennisJacobsenWildlife any focusing issues with the 12 to 40? Wondering if it's the lens or the body. Guess it would be hard to compare-don't do much birds in flight with the standard lens 😀
have you tried to give priority to stabilization instead of the speed of the burst, there is an option in this regard .obviously then the speed decreases
I remember that Mike Lane changed as well from Sony to the OM1 for BIF - with great results. Maybe you find some answers there: th-cam.com/users/MikeLaneFRPS
Thanks Mathias, i did see his findings and he also had similar behavior as i remember :) but i do get some great BIF photos as you can see here: instagram.com/dennisjacobsenwildlife the most recent shoots on my instagram are from the OM system gear it is just to bad i can only pick out a few really sharp photos in the burst series and i really dont like to shoot thousands of photos to be sure to some keepers. For now its okay but if i am in a situation where i just get 1 chance to get the perfect shoot i wouldn't trust this setup to be honest :) and thats a shame because i can deliver AMAZING photos when it hits the mark 100%
I have that lens. I have not tried it on my OM-1 but I do use it a lot on my M1X. It's not perfect but, I do get a good deal of sharp photos. Here is a short video I did. It was filmed with the 150 - 400 lens. th-cam.com/video/hZAlJ7fdVWg/w-d-xo.html

Interesting findings Dennis. I always shoot with the IS off at 50fps wide open at a minimum of 1/2000 sec shutter for BIF. What I find annoying with the OM-1 is out of a 25 frame burst I will get the first few frames in focus tack sharp and then the AF will drift for 3 or 4 frames then recover for maybe 6 or 7 frames then the drift will occur again. Others report a similar experience. I'm hoping this issue can be addressed by firmware upgrades. My experience with the R5 was that Canon improved the AF abilities quite markedly over the 2 years that I owned the camera through firmware upgrades. Wake up OM Systems!
