+1 for showing how it balances on the tripod and for showing stabilization results.

With all these great Sigma and Tamron lenses coming out, as a Canon RF user, my soul hurts more and more with each release.

😂Wonderful Chelsea’s face at 2:22 after saying “mine doesn’t suck”. Love you

You guys are great. I watch you because of the combination of technical information and practical advice, plus the banter between you two keeps it interesting. Sorry you felt you had to work with colds. I hope you recover soon. All the best.

Thanks Tony and Chelsea for keep posting all the wonderful educational videos even when you guys are sick! I noticed this from the beginning when Chelsea started talking. Please take good care of yourself!

Thanks for pushing through! Hope you’re both feeling better!

You guys along with chris frost and matt granger do the best lens reviews. Thanks for the work you put in for these reviews.

I had a Sigma 50-500 for over a decade and it was a staple on my 'car/travel' camera. I could take a photo of an elephant or the bird on it's back. Super convenient! Good to see this new 'update' option.

Great vid guys! Loads of useful info presented in an even-handed style. I'll be packing my extension tubes from now on after that scene on focus breathing. Keep it up!🤩

Hope you guys feel better. Thanks for the commitment to your craft and profession.

Nice work on the video. I’m new to your channel, I appreciate the way you both present yourselves and the gear. Thanks

This was an excellent comparison video, thank you very much for doing it.

Thanks for the helpful review. Hope you’re feeling better soon!

As always entertaining and informative for us hobby photographers considering lenses and cameras. Thanks!

Great review, thank you. I do not see bird photographers rushing out to sell their 200-600 however. The Sigma is heavier, much more expensive (here in the UK anyway), unbalanced on tripods, horrible extension to lens body when zooming, and a so-so build quality - all compared to the 200-600. The 200-600 is so well built, lighter, sharp, quick & silent auto-focus and at a a great price. I've never really used anything less than 200mm as a commercial bird photographer (wild birds) in 25 years. The 200-600mm is also very nearly comparable to my Sony 600mm f4 at f6.3 in terms of sharpness and autofocus speed.

I just want to say you guys are great. Informative and have great attitudes.

Sounds like you're both recovering from colds...you look energetic and happy so glad to see! Nice review video as well. Happy New Year!

Really loved the section starting at 9:00. I tasted a bit of the fun you get while doing bird/wildlife photography!

For me, the promary reason to have a zoom with 500 or 600mm focal length is to get the long end of the range. Getting the shorter end comes in handy, but I buy it for the reach and that's where I want the best performance.

Thank you for your very informative and helpful review on both lenses.

You both rock! Love you both and your so knowledgeable. Thank you for sharing 😀😀💕💕

Mine does not suck…lol. Major point as I recently sent my Sony 100-400mm GM in to be cleaned, which I also had to do with my Canons in the past. 99% of the time I personally use my 200-600mm at 400mm+ and love its balance. THANKS Sony for sharing your mount and giving us third party options like this.

You both look tired on this video, but still manage to give so much insight. Never shot wildlife, yet this informations were really good. Bravo

Send all the birds to me!!! Lol great comparison.

I really appreciate the detailed description and context you give your reviews! Also the humor is much appreciated. Damn seagulls.

Nice comparison, loved the Mark Smith mention :D

Good and useful feedback! Thanks

Great comparison! Thanks! Literally just got the Sony 200-600 and was worried when I heard about the Sigma but, after watching this, the Sony is a keeper (for my needs)! You guys rock and keep up the great work!

Loved the call out to Mark Smith lol! Great video.

many thanks for sharing great information...stay blessed

Superb review..waiting for time to compare these two lens ...Love from India..

9:00 I don't blame the birds. Mark Smith is aweseome.

Amazing review, and I have the 200-600mm and think it's the better one mainly for weather sealing. But might as well buy the Sigma if I get another Sony body or if I can only carry one lens as 60mm on a full frame is wide enough in most cases and the insane close focusing distance.

2:18 This entire video, beautifully summarized by Chelsea in three words.

Back in the day, shooting my daughter's softball games, the Sigma 50-500 was a game changer. I could cover all the bases and the out field standing at the same spot. Did not need to change positions. Loved the extra zoom range.

Great comparison video thanks! I see you have the same cover on your Sony as I do - what a bugger that cover on the lens hood was to get on! But happy with the RolanPro cover over all.

very interesting video, big like! Greetings from Italy

Great review. Chelsea, she's so funny. Thank you, guys .

60-600 is a great range for shooting baseball! I sometimes can't use my 200-600G because I can't shoot the nearest base or the batters. But what I really want is a 150-400/4 w/o image stabilization (for lighter weight). That way I can use the lens under the lights also.

Very nice👍👏💯 and thanks for sharing👍

A great video lots of info

The most significant take away from this video was that Sony limits the fps for 3rd party lenses. Thank you for this info! Also, I was about to buy a Canon camera this week but cancelled the order because of your video telling me about no 3rd party lenses for Canon RF. I appreciate your help!

I love that you are comparing the Sigma lens against Sony lens. Great job as you made me think outside of my, "Personal Box".

Great! Thanks! For APS-C shooters (since many wildlife shooters use APS-C specifically), the Sigma's ability to go down to 60mm is an extreme advantage. Glad to hear you're recovering. Have some chicken soup!

love your reviews!

Hey guys, great video! I am a hybrid shooter and was wondering if you did any tests with this on the video side of things as well? Would be very interested to see which is better for videos as well. Keep up the great work!

I have the 200-600 and when I want something more compact I use the 100-400 Sony or the 150-500 tamron. This new sigma looks good for people who only want one lens from short to long but the weight is off putting. It’s a do all the things slightly less well sort of lens but it looks sharp and well made. Such a positive to have so many good lenses from Sony and third parties. It’s good to see an improvement over the previous sigma 150-600 for Sony e as that was very disappointing AF wise. At the same price as this new sigma for wildlife the sony 200-600 still represents great value.

Thanks! Get better soon! What is the frame rate with the 7RV?

That was a calm review Chelsea trying to hold in her laugh after 2:18 lol

That is a great review as always. I wish I had a camera that could use the new Sigma. All I have right now is a Canon 7D and a 7D MKII

The results are interesting, I haven't ventured too far into that area of photography, but the few pictures I've taken were just with my smartphone and a teleconverter (which is almost like a 1500mm I think) and I'll definitely consider the Sigma presented when I get to is possible

Found the focus magnification range option on sig 150 600 brilliant for suddenly to close doesn't completely solve the to close factor but does good job of it .60 to 600 great idea range need less weight and non telescoping not to expensive .Jumping for that lens with decent imaging focus.

Super interesting comments on the use of tube extensions with big zooms. Have you done a comparison between extension tubes and teleconverters? When would the teleconverter have the advantage to justify the extra expense?

Awesome comparison 👏 👌 👍

Very useful thanks

I've used the Sigma 50-500 and Tony is correct...when used in the field over long periods of time dust does get in internally. I've used this lens all around the world filming wildlife professionally and saw this first hand. I tried to send it in for cleaning and was told that the internal workings had a sticky coating and therefore they are unable to clean the lens. Having dust spots grow as you zoom in created longer editing time! I'm looking forward to trying the 60-600

Thanks for the review ! Was wondering what are your recommended settings / methods to optimally track birds with the A1 ( tracking sensitivity , focus area , etc. ) ?

While the Sigma is great for wildlife, you missed the opportunity to discuss what to my mind is one of the biggest advantages of the extra range on the short side. If you are photographing sports (football, lacrosse, field hockey) the action frequently moves quickly from close to the sideline you are standing by to the far end zone, or vice versa. With this lens you can get close ups of both the quarterback throwing the pass 15 yard from where you are standing, and then the reception 60 yards away.

Hi, I watch you guys all the time and appreciate your reviews. I'm going out this Monday to take photos of Eagles for the first time and I am considering purchasing the Sigma 60-600 F4.5-6.3 DG OS HSM. Question, will it work on the Nikon Z7 and the FTZ adaptor? Is it an FX lens? I am looking at it because of the price. Is there a better lens option of me as a first time wildlife shooter? Thanks! Clayton Fox

Man I never thought of external zoom as sucking air in! That’s kind of scary lmao

Great review , Thanks. Is the Sigma 60-600 sharper Than the Sigma 150-600mm ?

Well done guys

Ironically, I tested their Canon EF version of that lens (on my R6) just two days before they announced the Sigma version. Honestly, even the DSLR version ain't bad at all

Excellent point about "Focal Shrinking" starting at 6:20 but I did not quite understand how and why that happens and why extension tubes are able to overcome it. Could you explain it in more detail or provide a link to any existing video. If the barrel is fully extended out in case of Sigma, how does a fully extended barrel become 300mm if the barrel does not retract back in?

You could mitigate the gimbal balance issue a bit with a longer Arca Swiss plate which would allow you to rebalance slightly faster by loosening the plate and moving the camera.

AWESOME video and so very informative! what was refreshing was no adverts!! I GET IT and i understand but sometimes 3 times in a vid is tiring LOL but I think i know what i will buy. so, do i stay Canon (reluctance) or go Sony A7R IV... not happy with Canon's stance on 3rd party lenses

wow, never knew how much focus breathing could affect those super telephotos, that's nuts.

Ooh, sounds amazing 👏🏻

I’m going to go with the Sony lens just because of when you zoom out its all internal and already have the 70-200mm 2.8ii and love that lens

i wonder how does it compare to the tamron 50 - 400 overall. tamron seems to be pretty sharp and quick, and im wondering if the extra weight and price is worth the +200 milimeters. but that stabe seems to be very nice, i would like to see how it performs for video, because the tamron is so so in that regard.

Great video. I want one of those. Oh, and what does "Fixed Zoom" mean in the the lens name: *Sigma 60-600mm f/22-32 Fixed Zoom*

2:18 Enjoyed that joke a little too much 🤣

Tony & Chelsea, I always love your practical sensible reviews and always feel I can trust them. Regarding the limitation in FPS (on the A1) I recently read Sony categorically claiming the limitation applied to third party lenses is the fault of those third parties and not Sony. However, that being said, is not limiting a product like this anti-competitive and anti-customer/consumer? I thought Apple had been penalised for the same activity?

I hope you both are feeling better soon.

What's your opinion on pairing this lens with Sony 6400 camera? picture quality? Is it worth it or is this lens ideal for a full sensor camera. Thank you

Very helpful comparisons for what is a quite difficult choice. What I am interested to know is if the Sigma lens will work with the likes of the Sony FX6/FX9 video cameras? I currently use the Sony 100-400 G Master with both and it works superbly as a video camera zoom lens using a zoom demand motor.

I notice the Sony is bigger diameter.Does that affect the difference in light that gets into the camera?

I REALLY love my Sigma 60-600 F mount lens. Now that I have switched to the Z9 I am curious as to whether this E mount one that you reviewed fits the Nikon Z9?

Okay Tony I'd like the review that you and Chelsea did it was good , so with the Canon mount model will that Sigma 60-600 on the Canon mount model will it work as good as the Sony one that you tested their .

Interesting review, thanks, but I am definitely sticking with my Sony 200-600.

Can you test the stabilization effectiveness of the 200-600 on the A7RV (which have sync IBIS for Sony lenses) vs Sigma vs Sony without sync IBIS? :)

Nice jacket!

I love the 200-600 because the focus is fully internally. The 60-600 external zoom is one thing, the weight another different things. My Sony 200-600 is sharp until 550-570 mm after which it becomes less sharpened

So...the Sigma is for mirrorless cameras? I missed that DC DN discussion at the start.

I assume not available as an EF mount... sad day! Would love this for my 90D. I'm trying to decide which zoom to buy for it.

One thing you missed. The A7R5 is the ONE body in the lineup that provides Sync Steadyshot which will easily equal the amazing stabilization of the Sigma. Too bad you didn't get the opportunity to see the A7R5 with the 200-600 in action. it's amazing now as well. Make sure you update the firmware on the lens for sure for those who have a A7R5.

Hi Tony, which extension tubes work the best with Sony 200-600 lens and A1 combo based on your experience?? Any link in the description would be helpful 🙏🏻 One more thing, if you can also do a Z9 with megadap ETZ adaptor with Sony 200-600 or 100-400 review that would be awesome .. Thank you 😊

Are these 2 the best lenses with those focal lengths one the market?

There is a sigma foot that comes with the DSLR EF version that you can buy seperate that is a long arca Swiss lens foot so balancing on a gmibal is easier even at 600mm.

Thank you for making my decision easier haha also nice to see some CT locals killing it!

Hello Tony & Chelsea, I am a wildlife photographer that does a lot of wildlife photography and videography in the backcountry of Colorado. I am planning to buy either this lens or the Sony in the near future. Due to my shooting style I really am interested in the sigma more because I like to shoot wide images of wildlife to show context and a scene as well as portraits of animals. The only thing possibly keeping me from pulling the trigger on the sigma is I’ve heard mixed thoughts about image quality. I will gladly switch back and forth lenses if it means the image quality will be noticeably better especially at the tighter zoom ranges 400-600. In your experience shooting with this lens in real world scenarios do you think it would be a noticeable difference in image quality that will make me regret not opting for the Sony?

Best used on a video type head or with the Gitzo dampened gimbal head. When I owned a 200-500mm lens I always needed to take a 70-200mm lens as well or I would have missed to many shots with 200mm at the shortest focal length. No mention of focus breathing with this lens.

2 seconds in and I'm predicting the sealed 200-600 comes out the better overall. Will edit if I'm wrong.

Good health to you! Thanks for the review. I wish Sigma would make a camera as nice as the A1. That would solve the 15fps issue. But I am glad Sony at least gives us a choice and for Sony A7R V or IV shooters 15fps is fine.

Guys, thanks for the video. I’m thinking about putting one of these lens on my Sony a 6700 for wildlife photography planning on doing a Safari in a year or two but that’s just one trip. which one would you recommend forthat camera? Thanks

Would you be kind enough to compare new fuji 150-600 along with sigma and Sony zoom lenses of the same range. Thank you

Does anyone know if this lens limits the frame rate on the Sony A7R family of cameras?

For sports a subtle but underestimated advantage of the Sony is the quick accurate short throw zoom. But that 60-200 range would be super nice when they run to the nearest base. The 200 on the Sony can’t be closer than about half a baseline. Does the sigma zoom in clockwise? The 100-400 was counter-clockwise and I never could wrap my head around it. Push pull works much better but still not near as well as the Sony zoom. Fast but harder to be accurate, always feels a little clunky.

I enjoy your videos and the way the product is tested. I have the sony A74 and learned a lot from the tutorial you filmed. This past week I bought the 200-600 from Sony and have yet to start shooting. You are a nice couple and wish you all the best of luck. I am 69 and can finally spend enough time shooting. Love you both. Fred van Schaagen from the Netherlands.

Good review from a Wildlife photgrapher points of view. Many times reviewers only do lab tests and not usablity. Beware of the fanboys that will say Tony and Chelsea are paid by Sony.
