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.

[@root9065]

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

[@christopherfrost]

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!

[@Kendye6]

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.

[@oconobee]

It's always great when you do these tests on the APS-C version too. It looks like it could be a good 150-600mm on this cropped sensor.

[@hardywoodaway9912]

would always prefer the 70-350 over this

[@Eikenhorst]

@@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!)

[@Skipsul]

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.

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.

[@shadda]

Can confirm, I've owned this lens for 2 months now and I use it on both my A7R3 and A6500. I sent my 70-300 tamron back.

I was looking forward to your review of this lens. I think your reviews strike a great balance between specs, real world shots and charts.

[@kian8382]

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.

[@networm64]

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

[@trym2121]

We have yet to know how the image on 7r4 which demands even more resolution through out the sensor than 24MP apsc.

[@networm64]

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

[@HR-wd6cw]

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).

[@erickquintanilla3420]

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.

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.

[@jarisalmenaho5431]

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.

[@gregturner_awod]

Excellent review with great analysis of the lens. I have pre-ordered from Sigma Australia. Thanks for a helpful review.

[@oscarcrendeful]

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).

[@biaowu5901]

Great review as always, cheers! btw, the new tamron 28-200 looks rather interesting, a review on that any time soon?

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.

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 ?

[@tosvus]

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.)

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.

i've been using the ef mount version of the sigma 100-400mm c on my M50 and its been brilliant from tubing and converting it down to get 2mm macro on the sensor to stacking converters so 2000mm+ telephoto. i'd be really interested in a direct comparison of this and the ef one when it comes out fully. maybe this might prompt sigma to make an m-m mount x2 teleconverter for the canon m when they make it for the system. i've been looking for an m-m mount x2 for a while. very much doubt i'd be changing my ef version for the m mount as i have canon origonal tubes and converters, i found third party ones too weak for the heavier lens. not sure how m mount tubes work fair with this one. great vid chris, if they come up with the 150-600mm for m mount that would be a delema as i yet to get that one on ef, though the higher price would make me think the ef mount more affordable

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!

I'd be curious to see autofocus comparison with native Sony lens for wildlife. Also sharpness comparison.

When is Sigma 70-200 2.8 DG DN coming out?

[@analogdesigner-Jay]

Christopher, shouldn't your mid zoom value be 200mm as opposed to 250mm? Isn't 200 the nominal log value between 100 and 400? Thanks for the world's best lens reviews!

Some people are never happy 😆🤦🏻‍♂️

for close-up image quality. could you standardize the testing distance (to say 100cm), and use your test chart? this will let us compare lenses that differ in minimum focus distance, and give us information about corner sharpness.

I am still waiting for some compact primes 300, 400 and 500mm !

Sigma should be making more Sony APSC lens. The trio fixed lenses F1.4 are all really good ones.

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?

[@Viking88Power]

Wondering the same

Check out my review of the 70-350 :-)

5:33 is it just me or does that rock look like a THICC T-Rex?
