Great review. Love the honesty, and real performance expectations.

Thank you for using the metric system for measurements and weight in your videos!

The best reviewer on lenses and cameras!

Great review!!

Gorgeous photos at the end.

Great Review!

Appreciate your thoughts on this lens. I like everything I see and hear about this lens. I think I'm placing my Sony FE 85mm F1.8 on the market, and getting the Sigma.

Thanks for another great in-depth assessment Dustin. My main interest in the newer lenses is how they deal with live Eye AF, and I'd really love to see you incorporate this into your tests. I think the era of manual-focus-only Cine lenses is due to be surpassed in this regard, and this capability will become a key buying point for a substantial chunk of the buying market.

Thanks Dustin, I now may semi-retire the boat anchor that is my 105mm Bokehmaster. Although I do enjoy the workout, I love the bokeh from this new 85mm and my new studio, I would be able to use the 85mm more often in the space I have.

Hi Dustin, Great video. What kind of Mic are you using? It sounds great.

I hope they'll make an RF version of this. Instant buy for me.

How do you feel like this relates to the Sony 85mm 1.8? Seems like a decent upgrade based on the video, but I’d love your thoughts

Great review. This lens has been getting lots of mind space lately. I re-watched your video on the Zeiss Otus 85mm. If the Zeiss is still the ultimate 85mm, how close would you say this lens gets close to that level?

Don’t have any Sony bodies but love your reviews and like knowing about how Sigma is progressing. They really seem to actually have been changing or accelerating the change In optical design . Pretty much all companies have followed the (followed) i said , the designs Sigma has made . It started with the art lenses for dslrs. All of them were bigger but pushing new optical designs . Now they started the same trend starting with the 35mm f/1.2 . Then started now working on building smaller. We saw them starting this (learning)with the APSC primes they made the 16,30 and 56. Sony is the master at this at the moment I think . Look at the new 12-24 f/2.8 as an example . We are going through a time period of new optical revolution and learning. Nikon is making ground in other areas and working on the smaller,lighter design theory. Not all of their lenses are but as a system whole . Canon is building beautiful but big and heavy f/1.2 glass . Tamron is pushing the limits on the image quality of lower end product. So everyone has their paths at the moment but it’s all working towards a more perfect image . Taking away as many imperfections all the way to the edges of the frame. Bokeh is getting softer too but I don’t believe always prettier but more techinal looking . The whole modern perfect look isn’t as pretty to me and I kind of like the imperfections in many old lens designs. This is why I shoot both modern and old (Nikkor ai , ais and non ai ) but also some of the latest Sigma art and Nikon e . I still have DSLRs though . By the way because of your review I just purchased the Sigma Art 28mm. I think it’s modern with some character. I a few months back got the Sigma Art 40mm . It has almost no character but perfection. I got rid of my Sigma Art 50 for this lens and now see where there was some character to the 50art . I’m still happy with my purchase.

Thanks for the great review ! I'm owning this lens, and am struggling with portrait autofocus, especially when backlighting the subject. Is this something you encountered as well?

I hope they release a similar version for Canon. It'd be nice to have a compact 85mm with high quality optics, the current one is massive.

Hi Dustin, does the lens actually move the aperture similar to a fully manual lens or is the aperture movement still controlled by the camera body based on the position of the aperture ring? Thanks!

Thanks for another great review. How does it handle flare, glare and loss of contrast in really strong back lighting. I'm a surf photographer and most of the time I'm shooting into the sun and need an upgrade to the Sony 85mm F1.8

Good review, how does it compare to the samyang 1.4?

Hi Dustin, thanks for making this video. I have been using the 85mm GM for a few years now and my main complaints are it's weight and focus speed (it's okay with posed shots but struggles with active kids). Does it make sense to sell the GM and get this lens? Depreciation hurts but I would be effectively be spending nothing for this "sidegrade".

With a third party lens like this on a Sony camera, will the camera still apply in camera corrections to fit it for vignetting, pincushioning, etc.?

I am curious how it compares to the new Canon RF 85 L f1.2 ? it seems to me it must be very close, but I wonder how close. you really praised the canon lens as being like Otus quality, and didn't hear you praise this Sony lens in quite the same way. so I am curious about your opinion, even if you don't actually do a side by side. even tho I would love to see a side by side of two portraits with a blurred out back ground. I am mostly wondering how the contrast and the separation from the subject compares, and the quality of the blur. considering that the Canon is over twice the price. but also twice the weight at 1190 gram. so other than the Canon being f1.2, does it have an image quality edge. because it definitely loses with it's Price, weight and size ( I can't wait for Nikon to put out a fast 85 )

Great in depth review as always! I do have a question, I'm seriously considering purchasing this lens & selling my 85mm GM. My issue is that the GM has a hard time focusing in low light conditions & the focus hunts in & out, it drives me crazy! I shoot mainly low key boudoir photography. Another thing is that the GM isn't tact sharp at f/1.4, I have to bump it up to f2 to get tack sharp focus on my subjects eye, so how does the Sigma 85 focus perform under low light conditions? Any input would be greatly appreciated...Aloha

9:57 and 10:06 uh...the old one is even noticeable sharper!! :S Nice that you have an old German 10DM banknote! :)

I still have the YUUGE OG 1.4. I love it's intimidating size when I want to impress (ignorant) people. It has a presence

A comparison with 85RF 1.2 would be fantastic , for you the canon is even sharper and better boekh ?

Are you planing to test the new Canon r5 & r6?

New Sigma 85 mm is like Sir Dustin.... perfact...

I know most of the reviews compare the Sigma 85mm DN with Sony's 85mm GM, but how does it compare to the Sony 85mm 1.8 FE? In your review last year of the Sony 85/1.8, that lens was already facing stiff competition. The Sigma 85mm DN is clearly superior to the Sony 85mm/1.8, but at twice the price and weight. Also, other reviewers have noted having to stop down the 85mm DN a bit to have better focus/sharpness away from the center. As a hobbyist, wondering if the 85mm/1.8 is sufficient to have in this focal length.

Yesterday I've tested Eye AF and focus speed on the SIGMA 85 1.4 DG DN ( Sony ). I have to admit I am quite disappointed. When the subject walks slowly towards me ... out of 10 photos, only 2-3 were in focus (all shoot on F 1.4). I've tried the lens on 3 different Sony bodies (a73, a74, and a7s3) and everywhere the same thing. I also tried it with different AF settings and speeds, good lighting conditions, backlight, etc. In comparison... the Sony 85 1.8 with the same settings ( shoot at F 1.8 ) and the same conditions missed only 1 photo of 10. Does any other Sigma owner have the same case?

I hope this philosophy extends to prime lenses and zooms that are really native to the sony system. I think about an update of mine with A7IV, sigma 14-24mm f2.8, 85mm f1.4, 50mm could be f1.2 and sigma could go for a 200mm f2.0 or f2.8. it would be a good discussion. My two cents

hi there . will this lens allow sony a9 do 20 fps ? thank you

Hello Dustin ! Hello you are in-depth reviews ! I am reviewing your latest video on the new Sigma 1.4 85mm Art lens for mirrorless cameras . What would it take for you to do a review with the Fuji xt3 xt4 with The Fringe ER lens adapter Canon mounted . To this new lens ? Your expertise in this matter would be greatly appreciate it ! Thank you ! ......Curtis

I have the Samyang 85mm 1.4. Does the quality of the Sigma warrant the price difference?

Is AF in video shooting as good as GM?

Hey, question how about for video is it good?

I hope they make the 50 like that size or less

Hi Dustin your video released today...how people did comments before three days

I was just about to buy the GM85, my investment in supporting your channel just saved me $800, TY MR A!!!!

Old Sigma 85 Art: Dustin's Definite reviews >>>>> New Sigma 85 Art DG DN: Dustin's Standard reviews.

At 13:38, I kind of have a problem with the image of the lady shown. Is that an example of the focusing or the lens or did someone edit the picture to look like that. Everything seems blurred out except the women, even the wall ahead of the subject are blurred. Weird!!

1:25 I have news for you mr. Abbott: a lens, and not even the Sigma, is tracking your face. That's your camera's job.

That fly on top of his head is really bugging me

Hi Dustin ..Swati from India

I love your written reviews, thank you very much. But I do think your videos are too long, so longer written reviews and shorter video reviews ;) I will also help the world with less CO2 when videos are shorter :) I only takes a short fraction of time to read a review, I takes ages to watch a video.

Terrible lens. Poor pin cushioning and focus breathing 6:04. Not sharp at close focus wide open! Should never have passed the design concept stage. Is there a problem caused by the short flange distance on these mirror disabled cameras? You looked very uncomfortable making excuses for Sigma Dustin.
