Smaller, & Sharper? Sigma 85mm f/1.4 DG DN 'Art' lens review with samples

It's great to see so many new lenses emerging which are specially designed for mirrorless cameras. Will this new, DG DN version of Sigma's astonishing 85mm f/1.4 'Art' lens further erode the legacy of older designs for digital SLR cameras - or will any compromises involved in reducing its size just erode its image quality?

I have had this lens for a year now. I am always blown away by its sharpness every time I use it. Owned Canon EF 85 f1.8, 85 f1.2L, 85 f1.2L II, EF 85 f1.4L IS, Sony GM 85mm f1.4 and honestly this lens is the best I ever had. Small and sharp and f1.4! It is crazy!!!

Genuinely one of the best portrait lenses I've ever seen. The bokeh is creamy, the colours dazzling, toggleable click, minimal technical issues that would bother me even with the test cards. Excellent review Christopher. It's always a good day when you've got another lens review up, if only to dream about which lenses to buy and enjoy your always breathtaking photography.

[@ParampreetDhatt]

Sigma clarified during the presentation that they were deliberately leaving vignetting and distortion for in-camera corrections as the optical elements required for handling these aberrations lead to a significant weight increase. I'm personally a big fan of this approach and hope more manufacturers do the same and make lenses lighter without really compromising more important aspects like sharpness, bokeh, CA, coma etc.

[@shawnbrynelson5333]

Wow, ive been very impressed by pretty much all the Sigma Art lineup but this is above and beyond. Making it smaller and lighter but with equal or arguably greater image quality is no small feat. Im especially impressed by the lack of color fringing at 1.4. I love the choice to have an optional aperture ring too.

Wait, what? How the hell did they cut the size pretty much in half and made it even better? This is absolutely jawdropping. For me this is the best 85 period if you consider price and performance. The RF 85/1.2 is amazing but you can get three of those Sigmas at cost of minor light loss.

[@jaschana2220]

The GM might be getting outdated, but the performance of the lens is impeccable. This sigma is great, but has many issue still that may make a bad option compared to the GM. 1) focus breathing 2) pretty bad pin cushion distortion 3) poor vingetting and fall off. Super sharp indeed.. but you gotta give it to sony for producing such quality glass like 5 yrs ago.

[@nicolask.3825]

@@jaschana2220 other than the distortion, I don't think the GM outperforms this lens in any category. Not to trash on the GM - I know rendering is a pretty vapid comparison, but I preferred the GM in side by side testing from some website - still, it has to be admitted that the Sigma generally outperforms the GM on a technical level.

[@VicenteSchmitt]

Seems to be a great lens! If I were Sigma, I'd laugh this for L-mount only as a way to push that system and only later release for other mounts. Having E-mount at launch sends a weird message.

[@ChimaChindaDev]

I completely agree.

[@N0rdman]

Sigma isn't too flush with money, even though they have the option of selling to several brands; that is why they need to claw back some money. The sales of L-mount cameras are dwindling in comparison with the E-mount and they badly need the revenue to continue to be in business like everybody else.

[@S3l3ct1ve]

Very nice indeed :)) Been looking for this lens, really love that they added the aperture ring. This is really a mirrorless standard 85mm 1,4f that, not the bulky heavy outdated DSLR designed lenses they were selling before. The big and heavy 85mm ART was one of the reason I sold it and bought mitakon 50mm 0,95f, although different lenses with different purposes, but that 85mm was damn heavy, shooting weddings or other occasions, you could really feel its tool on your wrists and that awkward weight distribution when you mount it on Sony A7 series body... nah hat design was purely for DSLR shooters... And this one looks very appealing.

[@panopsata3038]

Well, it would be nice if they could include it for all mirrorless mounts like the RF, Z, and X mount.

[@user-yk1ie5ep1i]

RF and Z eventually. FE and L mount are clearly the priorities.

[@Xetenor]

Sigma has nailed it finally while still choosing to not fix aberrations that are easier to correct. This lens with the 35 1.2 would be an amazing combo. Currently I am running the 35 1.2 and 105 1.4 and totally loving it. If sigma jumps on the RF mount (highly doubt they will just like nikon Z mount), it would be incredible. They would need to redo their lenses possibly unless they release the adapted versions. Literally what makes sony mount so attractive to so many are the 3rd party lens options. Sigma is just killing it! I am sure I will end up getting me a copy of this awesome lens to carry around easier. Glad I waited and didn't buy the GM. This almost makes the GM obsolete now at this price point IMO.

[@Whaever_1981]

How's the focus breathing?

It looks like we're going to stage, when image quality testing on lenses becomes pretty much to no purpose, as most of newer optics while hugely expensive, knocks to perfection.

[@mylucksmiles]

There is a now a new game changer when it comes to lens choices. lightrooms new upgrade for noise reduction. Why does it effect lens purchases. ? . Well for most photigraphers lightroom is a most have . I purchased the older sigma 35 DG art lens to use on my z 7.2 camera. I have the 24-120 z zoom but really i love prime .I was not impressed with the sigma 35 lens it does not perform well till you get over f 5 .6 and dies again after f 11. However the lightroom noise reduction when applied made a difference to some of the final picture quality.I Will be keeping the 35 for now and learn to work with its limitations. I know you only test lenses . However this new feature in light room does in a way a add on upgrade to picture quality, enough I would say to give some less expensive lens a step up. May be after or along side picture quality chat review a test via using the up graded noise reduction function , this would improve the lenses performance ..... I have personally seen some photos I would not normally have thought of using turned into nice photos ... After all it's the finished item in the end of a production line we are all after this new update is a means towards an end not a end in its self. Thanks for reading this.

[@jd3330]

Sigma has come a long way. I remember when they first came out with the 18-35 1.8. That lens put the Art lenses on the map.

[@NelsonMichael]

actually that belongs to the 35mm 1.4 art

[@jd3330]

Nelson Michael Vlogs sure but having a zoom (even for cropped) with that wide of an aperture was unheard of. Videographers loved the lens and amateur photographers enjoyed it too bc at $600, you can replace your kit lens with something waaaay better

[@fellowcitizen]

This lens has the same optical designer as the 18-35

[@Qlicky]

@@jd3330 35 1.4 at $899 was also unheard of, and it came a year before. I still have it, and if anything ever happened to it, I would get another one day after. The true grand daddy of Art lenses. Even today, 8 years later I dont think anything comes close to it in price/performance ratio. 18-35 while stellar lens, is crop only and thats a huge downside to professional photographers.

[@nicolask.3825]

@@bentierney-morrison5881 I still hope they release a new 35mm 1.4 dg dn, because that 35mm 1.2 is a monster - it's closer in size to the old 85mm 1.4 dg hsm than this new one. That's even more imposing when you consider that in a given line of lenses (Sony 1.8 FE, Nikkor 1.8 S, Sigma 1.4 DG HSM Art), the 85mm tends to be considerably bigger than the 35mm. Other metrics like price aside, the sheer weight of that 35mm 1.2 is prohibitive in a way neither this 85mm 1.4 dg dn nor a potential 35mm 1.4 dg dn could ever be.

[@bigdhav]

Isn't that just the phase detect system of the Sony a7r2?

[@vivalasvegas702]

Sigma must update or further refine their AF algorithms to match Sony, not the other way around IMO. I highly doubt, it’s the Sony phase detect problem, especially if it works fine with native glass. If that is fix, Sigma has a winner in its hands, hopefully RF mount gets it too.

@@christopherfrost I have owned A7RII, A7III, A7RIII, A9 and A7RIV and yes there is a significant difference in the autofocus with the newer generations of Sony cameras, not a minor difference. If you can afford the Z7 and Canon R5, you should make the investment or rent the more current Sony bodies to help make your tests more relevant. I love your efforts but this is the one area where you aren't getting the true E-mount performance and that denies viewers the full story. You are two generations behind in Sony autofocus improvements. Just rent the camera if you can. Not a single other reviewer is testing the latest E-mount lenses with a five year old tech A7RII. Current Sony cameras focus so much better. Cheers

So you are honestly, honestly saying that you think I should blow £1,000 on replacing my 42mp a7R II with a 42mp a7R III, for the sole reason that I can thereby satisfy you by showing a small difference in autofocus speeds, instead of merely telling the audience that it'll focus a bit faster on a newer camera body? Goodness me - you must be so rich that £1,000 just means nothing to you! You must be swimming in money! Are you currently supporting me on Patreon? If you were, then you might at least be beginning to justify your suggestion that I needlessly waste huge amounts of my family's money, just to show a minor autofocus improvement. And renting gear is just as expensive, and even more wasteful - if I rented a camera every time I made a review then each video would cost me £100 to make, and I'd be left with nothing for it. Incidentally, one of the most scientific and well-respected lens review websites - Lenstip - uses an a7R II for testing, too. And why have you owned all those cameras, anyway? You must have wasted so much money yourself constantly upgrading every time a new camera body comes out - it would cost a fortune needlessly purchasing every incremental upgrade. Not that it's any of my business how other people spend their money...

@@christopherfrost you can frame it anyway you want, but the lack of your testing on current bodies diminishes your content. It is your choice.

Be aware that third party lenses are often limited by using only EF lense registry numbers that basically lead to those lenses behaving like old EF lenses. Depending on which number is used, they can even be limited in focus area and other things. Not to forget that features like high speed viewfinder, focus stacking, lense corrections or firmware update via camera won’t work. Inder this circumstances I would better wait for forthcoming cheaper native RF lenses like the new 85RF IS

They would need to reverse-engineer all the X-mount electronics. Wouldn't be easy. They've already figured out E-mount, and they are native on L-mount, therefore we see them releasing lenses on those mounts.

@@TerabitTech Wrong and 'figured out' isn't the correct term. E-mount has been open from early days. L-mount is sigma own alliance. X-mount recently has been opened again as well.

It's nice to see you doing pre-release testing as other bigger reviewers: it means you're gaining reputation in this space. I believe it's well deserved. For what concerns the lens, I like it a lot, although being on APS-C I'm probably not the primary target of this lens. Anyway, distortion corrections may degrade corner sharpness, so that's a thing I would have liked to see better explored/clarified in this review. The optics look fantastic, and I like they reduced purple highlighting. I believe that this lens will be a great fit for a Sony a7R IV, but I'm wondering why they're not pushing out F/1.2 stuff (especially considering they are native on L-mount and need to compete with native RF glass). I believe they'll also redesign other full-frame lenses, but as an a6100 user, I mostly hope that they'll pay more attention to the APS-C market: their 16mm F/1.4, 30mm F/1.4 and 56mm F/1.4 for APS-C are great lenses, but we need more options, especially talking about zoom lenses. For example, they haven't revamped their 18-35mm F/1.8 on mirrorless mounts, and there are no 16-55mm F/2.8 or 55-200mm options. I'd also like something wider than 16mm and longer than 56mm (like 12mm-equivalent and 105mm-equivalent).

That lock button alone is almost enough for me to trade my GM for it

[@christopherfrost]

I love that lock button...

[@looshkaa]

Will this lens be available for canon ?

[@ramimxss]

the 85 1.4 is probably on par with the 135 1.8 in terms of sharpness. Would love to see a comparison though

[@IanWilkinson]

An extremely impressive lens and a much more attractive proposition than its bulky Otus-like DSLR-based sibling. If there's a 135/1.8 version in the pipeline, that might even give the 135mm GM lens a fright.

[@TekleHunde]

I trust your review, its simply the best

[@KameswaraRao]

I sufferd lot with weight of ART . Seems this would be my chocie some time latter ..

[@grat2010]

Looks fantastic. Thx for the review

[@shathan.10]

Hello, from ur experience, I wanted to ask u about bokeh comparison in sigma 85mm f1.4 lens on both apsc and full frame, which camera will result in more bokeh? I know that full frame is better in bokeh but considering the compression we get from the crop factor on apsc in the 85mm distance will that result in more bokeh than using it in full frame body?

[@LetiB76]

How does this lens compare to the Amazing canon ef 8fmm 1.2ii ...? I own both systems , and currently own this lens and love it ! However, I don’t have an 85 on the canon side and many photographers swear by the 1.2 ii .... your thoughts on experience would be appreciated, since you’ve used both ? Or perhaps a video comparing all 85s such as your macro vids ... thanks 🙏

[@johnstarkey4959]

Hi Christopher, I’ve just purchased the Sony a7cmkll , the sigma 85mm lens is three years old now , SO would you still recommend it today , especially as the a7cmkll has AI auto focus , TIA .

[@shawnlmchan]

Hi Chris. Could u please compare the image quality between this Sigma 85mm F1.4 with Canon RF 85mm f1.2?

[@tonyvalqta]

Hello Christopher! Im in dilemma - Please help me - If budget is not an issue, which would you choose- Sigma 85 .14 or Sony 85 GM - Which is better choice? Please tell me !

[@martin9410]

You get the same quality at a much cheaper price with the Sigma

[@pianoman1973]

Thanks for the review - I got a little confused though - at f1.4 you initially showed it's pretty sharp , but then when you moved to the photos you showed it was pretty soft .... since I would mainly want to use this lens in portraits at 1.4 and have it tack sharp at it - would you not recommend this lens ? How does it compare to the 85 1.4 GM ?

[@michaelbell75]

This is quite a bit sharper than the GM wide open. Watch Manny Ortiz compare this with the GM. He admits and proves this lens is better and he loves the GM. The only 85 that can touch this is the RF 85 f/1.2 and that’s $2,800. I shoot portraits professionally and I’ve owned many 85s on multiple mounts and this is by far the best.

[@pianoman1973]

@@michaelbell75 I've bought this eventually and am finding the eye AF hit rate to be pretty low when shotting backlit for mildly moving subjects.. Have you had a similar experience ? Am pairing it with the A1. Thanks

[@arunmohandas9127]

Can u show us the bokeh with an apsc camera too...just to get an idea about how the portraits come out

[@pkoeniger]

Hi Christopher, thank you again for this great review. I received the lens two weeks ago and just love ist. Sharpness and overall quality are the best I have seen. However, one thing irritates me: When enabling lens corrections in Lightroom, there is a huge jump in how the image is presented. It suddenly pops out of the screen, almost like a wide angle effect. Is this normal? Thanks, Paul

[@josepheveson6187]

What would be the best 85mm for bokeh on Sony do you think Chris?

[@wanhl2440]

This is crazy. It's like zeiss otus 85 1.4 with half the size, 1/3 the price, AF (with distortion but that is corrected in camera)

[@johnsoncityaerialphotograp7201]

This is the 85 1.4 I think we’ve all been waiting for.. I’ll be picking it up.

[@joseallende8046]

That lens is tiny compared to the original! Man, I hope they make these improvements to the rest of their Art line. Size was the only down side.

[@lalitdewangan7830]

Plz make a full review for New Tamron 28-200 zoom lens

[@rollandelliott]

0:50 wow wow wow can't believe how much smaller it is!!!! mirrorless advantage. however I'll get the old one cause its' cheaper! lol.

[@garypardyphotography]

That extreme bottom right corner! Way to shake up the formula! :D

[@dlee13]

How do you like it compared to the Samyang 85mm that you reviewed?

[@Garrythegoat1]

So wait is this for the sony full frame ?

[@trym2121]

No, for apsc. It can cover fullframe if you give beer to the lens

[@AndrewWithey]

Yes

[@berndpape407]

very good-thank you !
