Finding this video 2 years after upload - exactly what I was looking for. I had a Sigma 150-600 previously and it worked great. Obviously you can spend more, but for my use, I can't justify $2.5K on the Sony lens. If photography were a bigger hobby, maybe, but sometimes I go weeks/months without using it. I'll be pairing this with a Sony A6600 which is 3.6LB - very light. My prior setup - D500 w/ Sigma 150-600 - was 5.9LB. Weight savings is mostly for my sister - she loves birding, but had trouble with the heavier setup, especially if holding for a long period. She'll enjoy this one. Thanks for the thorough review.
Sigma and Tamron need to thank Sony for: (a) giving them the necessary tech info to make nicely compatible lenses (unlike some other makes); and (b) having a market large enough to be worth creating for!
It simply shows, yet again, how poorly Sony treat it's body owners by providing reasonably priced native glass. Just don't mention how Sony ,by default, left it to Sigma to provide glass for the hugely successful Sony apsc range.
I guess Im asking the wrong place but does any of you know of a tool to log back into an Instagram account..? I was dumb lost the login password. I love any tricks you can offer me.
Thank you very very much for this review! Before buying a new optic I always search if you reviewed it. You're of immense help, thank you again and keep it up the good work.
Even though this is an old review, it is still valuable for the information, I just bought one used off this videos' information, I always check your reviews before buying new or used. Thanks for good stuff.
Chris how are you liking the lens? I just ordered one yesterday to pair with my Lumix S5ii. I just needed something to take pictures of my boys playing soccer so I definitely didn't need anything more expensive than this.
Hell of a lens! *Humble suggestion for your future videos* - in the bright light reflection part of the review (11:39), would be nice to see how good of a job the lens hood does because their design differs with each lens. Couple other things you could mention is whether a firmware update on the lens changes anything, or what version you tested the lens at, and on the photo samples, you could write very small in the corner of the screen the SS/ISO/F-stop settings for that photo, and/or focal length where applicable. Keep up the amazing work, I have been your ambassador on Reddit :D
I'll try and think about that, but frankly...the lens flare section of my tests is fairly unscientific, so it might be tricky for me to find careful and fair way to do that, hehe :-) Generally though, with this lens, I only found any kind of problems when bright lights were directly in the image frame, so a lens hood wouldn't help in that respect. With firmware updates, I try to review lenses quite early, before the firmware updates come out. But I do sometimes mention them in the description (see my review of the Viltrox 33mm f/1.4), so keep an eye out there. Thanks for the comment, all the best!
@@christopherfrost Thank you for following up on my message :) fairly unscientifically or not, a lot of people in here swear by your reviews - myself included! (no pressure :D) Godspeed!
I already have the Sony (and love it) so would not want to trade out at this time, but I am very glad to see such a high quality competitor on the market now. Superb review as always.
What a beast is this lens indeed! Never seen a fullframe telephoto lens works on an apsc on par if not saying better! Wow! A brilliant early review Chris! Thanks alot
Well said...that would be around 27mp crop sensor! Who else needs the 1.4 teleconvertor then which I think will reduces the image quality somewhat more than the crop mode on a7r4
The thing about Sigma is that they know how to make a lens that feels good to hold and is nice to look at, too. Nowadays, high quality optics are just not enough to distinguish 3rd party manufacturers from each other because it seems that they all can deliver. Sigma pulls ahead of the pack with well-finished lenses.
@@hardywoodaway9912 Indeed, it is almost double the weight of the 70-350mm and also more expensive. That seems excessive for 50mm extra reach. But this lens is now also available on X-mount, where it competes with the 70-300mm and it seems people are happy to choose this one instead for the extra 100mm reach there. (on the other hand, this full frame lens is lighter than Fuji's 100-400mm aps-c lens, but that one is f/5.6 at 400mm, but it does show that in general Fuji builds very heavy lenses!)
@@hardywoodaway9912 Size wise or quality?. Because i've seen incredibly sharp photo's from this lens. The extra 75mm isn't unsubstantial when you photograph small birds.
i wanna take the time out to say thank you chris i mean seriously you’ve been really consistent with the uploads on lenses i didn’t even know were releasing now i have to get my wallet ready lol
Generally the sport mode for lens stabilization (in this case would be mode 2 on this lens) only stabilizes the lens when the shutter is clicked. Mode 1 on this lens (which is like Normal IS/VR modes on OEM brands) will stabilize the viewfinder as well but I think the effectiveness when the picture is taken is less (so you run a higher risk of of a soft image than you would with mode 2). That's really the trade off. For Nikon's, it's like using the Normal and Sport modes (Sport would be Mode 2 in this case, and Normal would be mode 1). You just have to decide which mode is best for the situation. Generally I've found Normal modes to work best if you're trying to photograph something still and you are still (you're just trying to counter any slight movement from hand holding on a fixed subject), and Mode 2 is for if you're not still (say your on a boat, or youre panning).
It's truly amazing what Sigma could achieve within such a relatively affordable and small package. This on APS-C could be a lighter 150-600 replacement, I'm only hoping Sony can improve their PDAF system for using smaller aperture lenses.
@@mistermadsen if you are thinking 100/2=50 and 400/2=200. 50+200=250mm. Makes sense but in my head it should be 200mm calculated from the max zoom range. How would tou call halfway on a 18-400 lens then ?
Thanks for you nice objective review. Following our review I bought it had originally been thinking about Tamron 70-180. Very impressed. One nice we touch is that there is a raised blob the the index mark is for the bayonet mount unlike Tamron lenses which only have a white line. This was very useful the other night while out in dark trying to photograph Comet Neowise.
Just wanted to say thank you for the detailed tests in the video - 3 years later, I'm shooting the solar eclipse with this lens, and was trying to choose between, ironically enough, my A7RII and A5100 and determine best aperture settings. On balance, it looks like I'll be shooting it at 400mm with the A5100 at f/8 - fingers crossed for good results!
Very interested also. Been looking at picking up the SEL70350G the last while and this arrives with good performance on APS-C. Not a huge difference in price either
Thanks a lot for this test, Chris; I wouldn´t have expected this sharpness from a C Lens but rather from an A Lens. I definitely concider buying one for my A7RII, it absolutely fulfills my expectations and hopefully those of my finance minister 😉.
Point of information about the Sigma teleconverters - they are for L-mount only. Perhaps they'll develop E-mount versions in the future, but don't count on it! Right now, the only teleconverters you can buy for Sony E-mount are Sony's own, very expensive models - which are designed for exclusive compatibility with a limited set of (mostly, very expensive) Sony lenses.
Absolutely amazed at the optics in this lens! For the money, this is the lens to buy if you don't already have a nice zoom in that range. I might even grab one for a lightweight alternative to my heavy 2.8 G-Lens. Great review again...thank you!
I'm torn between this or the 150-600 for L-Mount. I guess nobody can tell me what to choose, but in terms of pure quality, which one do you prefer if you tried both? (On other points the price and portability is a big plus, though the 150-600 has a considerably longer reach and is brighter at every comparable focal length, plus better weathersealing.)
Hi Christopher. I’m considering this lens or the Sony 70-350 lens for wildlife and general photography ? Which would you choose for a Sony A6400 camera ?Thanks .
Another reviewer said the 100-400mm was much heavier than the 70-350mm. I have the 70-350mm and been taking photos of birds in the last 2 months. About a third of the time I wished I could have had a longer zoom, but unsure if the extra 50mm focal point is worth the weight difference.
Hi Chris. I’ve purchased this fantastic lens after using your review as a guide! I’m thinking of purchasing a teleconverter for increased reach. Do you have any input as to whether the Sigma TC or the Sony TC would perform better? TIA!
Hello Christopher... sorry the Sigma bag you are taking out from the lens at the very initial part of the video, is it an aftermarket item? My lens came into a cardboard box without any accessories but the sunhood.
Hello Chris! Love you videos. I listen to them to help me relax while I'm working. Was wondering if you could do a review of the Sony 20mm f/1.8? For its price point, I've heard great things!
Looks great. Also looks more compact than a EF lens + adaptor setup. I currently have the Tamron 100-400 EF adapted onto the EOS R. I'm quite happy with the results but one of these as a RF mount. I might be tempted to sell and upgrade from the Tamron.
Awesome in-depth review yet again. Just 1 question I have, are the focal lengths mentioned on the test card the value on the lens barrel or is the crop factor added/compensated (X 1.5 or X1.6)
Nice video. Your videos are always very useful. I have a question. Why do you use that intermediate points of focal lenths? I mean, the middle between 100mm and 400mm are 200mm, not 250mm. In focal lenght terms, distances are proportionals, not absolutes. Between 10mm and 15mm, it is a huge difference. Between 400mm and 405mm there ist't any (in this case, 600mm would show the same difference that in the 10-15mm example).
@Christopher Frost Photography , I’ve compared your test 70-350 G OSS and Sigma 100-400 Sony E on A5100 (apsc) simultaneously on two the same monitors. In my opinion the better quality (sharpness, contrast) for apsc offer the 70-350 G OSS. Could you be so kind as to tell me your opinion in this case? Thanks. [ Great movie as always :-) ]
I just got my copy of this lens yesterday. I'm using on my A7RM2 (firmware 4.0) and I'm completely surprised by the fact that the Eye-AF function doesn't work (I get the "Invalid with the lens" warning). Most other reviews (all using A7M3) say that Eye-AF works fine and now I've seen your review using an A7RM2 and still getting Eye-AF... My camera firmware is 4.0, and doubt that is the issue. I've also noticed that the sharpness of all my shots isn't anywhere close to those I'm seeing on various reviews, including yours. I haven't seen any comments about there being bad copies in circulation, and I've been fortunate to never having had a bad version for any of the many other lenses I use. Any thoughts ?
Hey Chris. Great review so cheers for that. Going by pure image quality alone how would you compare this with the Tamron 70-300? I know the Tamron's corners are bad at 70mm. I will use one of these on a tripod only, for landscapes. Obviously I'd prefer the lighter Tamron but not at the cost of IQ, especially if the difference is more than just minor. Thanks.
It's wont be intresting at all. 50-250 Z is 250 mm at long end vs 400 mm . it's Insane difference. It's like you want to compare 24-70 to 70-200. Or at least 70-150...
@@UnluckyNewbie No it's not. 250 mm APS-C is similar to 400 mm (375 mm) full frame. I would be interested in how an APSC lens compares to a full frame lens. Important if you have to decide between going for full frame or staying APS-C.
Hey Christopher, I was wondering if you could do a list of the best wide angle lenses. I am in desperate need of a better wide angle, and your videos are amazing!
I have had the lens for a few days. Unfortunately, the front lens barrel extends automatically when the lens is held down. Is that the same with your example? It's quite annoying, unfortunately. Many thanks in advance!
I was saving up for the Sony 70-350mm that came out end of last year. Should I just switch over to this lens? What are some of the pros of the Sony over this one?
It's a very intriguing lens. I've loved my 70-200 GM, but I've found myself in some situations photographing occasional wildlife or details in landscapes where I want more want more reach. I'm considering a 2X extender, the Sigma 100-400, or the 100-400 GM. The Sony 200-600 is also under consideration, but I'm concerned it's too big to want to travel with or carry around just in case. I'm leaning towards the Sigma, but have plenty of options to consider and don't need to rush on a purchase.
after release there should be more comparisons between that sigma and sony 70 200 gm x2 or sony 100 400 gm. at least I hope for that. pls let us know your decision ;-)
Hope Sigma got their quality issues fixed. Had previous bad experience with a 120-300 2.8 and 100-400 C, both optically superb but the motors died in a while for no reason.
I have the new Sigma and other Sony GM OSS lenses and Tamron 150-600mm. I do like the light weight of the Sigma compared to the Tamron. The Sigma OS doesn't seem to be as smooth as the Sony OSS on both apsc and FF Sony cameras (for video work). The Sigma edge sharpness on stills is a bit strong that pics of deer in the grass don't seem as natural as other lenses. Welcome your experience with the Sigma vs Sony GM lens ? Thanks
Hi, I just got this lens a week ago and I am noticing that the autofocus when shooting in video mode is veeeery slow compared when shooting photos. I mainly do videos and this seems to be an issue for me. I tried it both on my a7iii and a6600 and had the same experience. Have you had similar issues? I also haven't updated the firmware of the lens from 1.0 to 2.0 since I have to ship the lens for that. Thanks!
Anyone else just watch his reviews as a stress reliever? Seriously the most soothing voice on TH-cam

Nice review, Christ. From your perspective which one is better for apsc, Sony 70-350G or this. All things considered.
Sigma 100-400 for sure! You can buy 1.4 TC for it soon! And dont forget when you buy Full Frame you wont need to buy another lens!

Get Sigma, Sony 70-350 is better for reach, price & weight but it will struggle a bit when it gets dark.

I am still waiting for some compact primes 300, 400 and 500mm !
Awesome in-depth review yet again.
Just 1 question I have, are the focal lengths mentioned on the test card the value on the lens barrel or is the crop factor added/compensated (X 1.5 or X1.6)
Nice video. Your videos are always very useful.
I have a question. Why do you use that intermediate points of focal lenths? I mean, the middle between 100mm and 400mm are 200mm, not 250mm. In focal lenght terms, distances are proportionals, not absolutes.
Between 10mm and 15mm, it is a huge difference. Between 400mm and 405mm there ist't any (in this case, 600mm would show the same difference that in the 10-15mm example).
Hi Chris, I heard the TCs only worked
with L mount, is that true?
They're releasing TCs for L mount first. My guess is that E-mount ones will come eventually
@Christopher Frost Photography , I’ve compared your test 70-350 G OSS and Sigma 100-400 Sony E on A5100 (apsc) simultaneously on two the same monitors. In my opinion the better quality (sharpness, contrast) for apsc offer the 70-350 G OSS. Could you be so kind as to tell me your opinion in this case? Thanks. [ Great movie as always :-) ]
They seem very similar to me TBH - perhaps the 70-350 might have a slight edge on an APS-C camera
@@christopherfrost Thanks for your opinion.
I just got my copy of this lens yesterday. I'm using on my A7RM2 (firmware 4.0) and I'm completely surprised by the fact that the Eye-AF function doesn't work (I get the "Invalid with the lens" warning). Most other reviews (all using A7M3) say that Eye-AF works fine and now I've seen your review using an A7RM2 and still getting Eye-AF... My camera firmware is 4.0, and doubt that is the issue. I've also noticed that the sharpness of all my shots isn't anywhere close to those I'm seeing on various reviews, including yours. I haven't seen any comments about there being bad copies in circulation, and I've been fortunate to never having had a bad version for any of the many other lenses I use. Any thoughts ?
Hey Chris. Great review so cheers for that. Going by pure image quality alone how would you compare this with the Tamron 70-300? I know the Tamron's corners are bad at 70mm. I will use one of these on a tripod only, for landscapes. Obviously I'd prefer the lighter Tamron but not at the cost of IQ, especially if the difference is more than just minor. Thanks.
Mine gets delivered on the 7th!!!
Hi Christopher, thanks for the video. This lens on the a7r2 works eye autofocus?
would be interesting to see how it compares to Nikon's 50-250 Z APS-C lens. About 1/3 the weight and price ...
It's wont be intresting at all. 50-250 Z is 250 mm at long end vs 400 mm . it's Insane difference.
It's like you want to compare 24-70 to 70-200. Or at least 70-150...
@@UnluckyNewbie No it's not. 250 mm APS-C is similar to 400 mm (375 mm) full frame.
I would be interested in how an APSC lens compares to a full frame lens. Important if you have to decide between going for full frame or staying APS-C.
I just bought the ef version 6 weeks ago for my Sony A7 🤦🏽♂️ now I will wait for a 70-200 f4! :D thx for this great review!
I was about to by Sony 70-350mm today, but now wait till it comes in market; compare both and make a correct choice.
Hey Christopher, I was wondering if you could do a list of the best wide angle lenses. I am in desperate need of a better wide angle, and your videos are amazing!
For which mount?
@@amitkrupal1234 Canon EF and or EF-S would be nice
Are the Teleconverter also available for e-mount?
I have had the lens for a few days. Unfortunately, the front lens barrel extends automatically when the lens is held down. Is that the same with your example? It's quite annoying, unfortunately. Many thanks in advance!
Would you grab this sooner than the 150-600?
need this one so badly for Nikon Z 🤩
The rubber band is a creative solution!
I was saving up for the Sony 70-350mm that came out end of last year. Should I just switch over to this lens? What are some of the pros of the Sony over this one?
Wondering the same
Check out my review of the 70-350 :-)
It's a very intriguing lens. I've loved my 70-200 GM, but I've found myself in some situations photographing occasional wildlife or details in landscapes where I want more want more reach. I'm considering a 2X extender, the Sigma 100-400, or the 100-400 GM. The Sony 200-600 is also under consideration, but I'm concerned it's too big to want to travel with or carry around just in case. I'm leaning towards the Sigma, but have plenty of options to consider and don't need to rush on a purchase.
after release there should be more comparisons between that sigma and sony 70 200 gm x2 or sony 100 400 gm. at least I hope for that. pls let us know your decision ;-)
I just got this exact lens same lens mount and everything but I didn't get a lens case?..
Great review as always..
@4:21 don’t forget to charge the camera chris 😂😂😂
Hope Sigma got their quality issues fixed. Had previous bad experience with a 120-300 2.8 and 100-400 C, both optically superb but the motors died in a while for no reason.
Oohh thats not good..😳😳😳...i hope by now you already resolved the problem of the motor??..😁👍
I have the new Sigma and other Sony GM OSS lenses and Tamron 150-600mm. I do like the light weight of the Sigma compared to the Tamron. The Sigma OS doesn't seem to be as smooth as the Sony OSS on both apsc and FF Sony cameras (for video work). The Sigma edge sharpness on stills is a bit strong that pics of deer in the grass don't seem as natural as other lenses. Welcome your experience with the Sigma vs Sony GM lens ? Thanks
That's really sharp lens wow
Please Christopher, make a review with the 1.4 and 2.0 teleconverter! Keep doing your great job!!!
Hi, I just got this lens a week ago and I am noticing that the autofocus when shooting in video mode is veeeery slow compared when shooting photos. I mainly do videos and this seems to be an issue for me. I tried it both on my a7iii and a6600 and had the same experience. Have you had similar issues? I also haven't updated the firmware of the lens from 1.0 to 2.0 since I have to ship the lens for that. Thanks!
