Christopher, the edge issues that you are experiencing on the Sony is due to the differences in the sensor stack thickness between the different cameras. The thickness of the glass in front of the sensor is optically significant, and lenses designed for a particular mount are designed such that they give optimal performance with a particular range of thicknesses. Once you stray outside that range, you can see sub-optimal behaviors, especially in wide lenses and in fast lenses (and doubly so in wide, fast lenses). This can range from under/overcorrection of spherical aberration, astigmatism, comatic aberration, or as it seems in the case of the Sigma 14mm, field curvature.

[@dzsemx]

Nashtok I was thinking the same

[@stakstonkvinge]

This is a plausible explanation. Another explanation could be the design of micro lenses on the sensor glass, which are designed to divert angled light from the lens down into each pixel of the sensor. Since Sony has a shorter flange distance than Canon and Nikon, the micro lenses are designed to divert different angles than the ones that are coming from a lens designed for a longer flange distance.

[@hzubovi1]

Can this lens be made to work with Sony's a7rIII or no?

[@BrianIrwin]

Sure, with the same issues called out for the A7RII I would imagine.

[@burtjohnson3848]

B&H have a Sony E-mount version of this lens as of today (just arrived). (Aug 8, 2018)

[@ericdennis5620]

Fantastic reviews. I've adjusted how I use my lenses. Knowing where the lens faults are can be time consuming. Definitely a channel worth following. Thanks.

[@ArthurFinny]

The Sigma art lenses are killing it! Great lenses and a great video!

[@Bacms]

Unfortunately, they are still riddled with focus problems. So there isn't much point in having all that sharpness if it keeps getting the focus wrong

[@ArthurFinny]

I have noticed that it gets confused in low light, that is a shame, really!

[@johncastle95]

Bruno Santos to be honest after using it on a Sony A7iii it is an amazing lens with great manual focus capabilities!

[@_FiDeLCAsTrO_]

@@Bacms I've configured my AF Profiles on camera for my sigmas, cuz they do have those focus problems. But after creating a profile for each... they don't miss often anymore

[@ArthurBrownPHOTOGRAPHY]

I do love the Sigma Art Lenses. My 35mm f1.4 gets used a lot. My only experience with 14mm lenses was the Canon EF 14mm f2.8 II. I was so disappointed with the image quality that I sent it back. The lens was very unsharp at the corners and had severe chromatic aberration on the left hand side of the image. It went back to Canon for testing and they said it was normal performance for that model! This Sigma looks a lot better. The lack of filter fittings would be a deal breaker though. Whilst I do not use filters a lot, I do use NDs & grads on wide angle landscapes. I am surprised there is no rear filter holder. The Sigma 15mm f2.8 Fisheye had a rear filter slot. After I got rid of my Canon 14mm I bought one of the first Irix 15mm f2.4 Blackstone lenses when they first came on the market. This lens is not auto focus but is extremely sharp right across the frame and takes both front & rear filters although the 92mm front thread means filter prices can be eye-watering. Keep up the good work!

[@petersuvara]

5 years later... still an amazing lens for all camera mounts.!

[@johngray9434]

I took delivery of this yesterday for a commercial shoot. The best £1400 I’ve ever spent. Stunningly sharp images with the Nikon D850.

[@andrew1977uk]

I wish Sigma would bring out lenses for Fujifilm! They always produce interesting lenses.

[@andrew1977uk]

They don't. You can get adapters for fujifilm, but you won't ever get the native sharpness.

[@alphatumeric]

Andrew C That's because Sigma doesn't have contract with Fujifilm to produce their lens. Have not heard any development from these two companies.

[@andrew1977uk]

Yup, there are a lot of theories I have heard in regards to them not producing gear. Although now that Sony has support, it's got to be a matter of time before Fuji gets some love.

[@miamidolphinsfan]

Thank you Christopher for the new review. I may have to do the "weekend hire" for this lens too. Hope you and the Mrs had a very Happy Easter. He has risen !

[@Stefan1968ful]

This lens is primarily for Astrophotography and here it really shines. I use it for taking pictures of the Aurora Borealis in Northern Europe. If you are into Landscape, you wont use 1.8 but more 5.6 or 8.0. So no need for this lens of you are into Landscape only. In my opinion.

[@quincylee2276]

I know I’m late, but thanks for your input. I’ve been looking to purchase an ultra-wide exclusively for Astro, and this lens seems like the top contender.

I have been waiting for this review! Awesome job, I just wish the shooting conditions were better for your astrophotography test haha! Looking to rent this lens before I think about dropping the $1,500

[@diegorivera2711]

The infinity focus could be corrected using the sigma lens dock. As a rental lens, maybe somebody changed the settings for its own camera or purpose, and never set the defaults back? Nice review. Keep it up.

[@jefffenske1958]

How can the lens be changed in any way, other than by taking it apart and fiddling with it?

[@diegorivera2711]

Jeff Fenske Sigma makes an USB dock that you connect to your pc, and, using sigma's software you can update the lens firmware, and also change the relative focus points (i. e. make the focus motor move to other position at X point in the focus scale) kzbin.info/www/bejne/mqHOdX2ens6XbsU

[@jefffenske1958]

Thanks, I wasn't aware of that. That could easily explain why the focus settings were off.

[@Urrofi]

i love your reviews

[@TheMetalButcher]

Holy Balls. Might have to bump some on your sharpness list. I'm not sure why someone would buy this for aps-c, it costs so much when you could buy a FF and a 24mm F/1.4 for less.

[@Coollok100]

Have heard of somewhat similar issues when adapting wide lenses to Sony FE mount in general - no idea why this happens but this isn't an isolated incident

The adapter may effect the corner issue. Also there is a solution posted elsewhere involving checking corner focus in live view.

[@pwprochazka]

this is a great review. Well done.

[@IanWilkinson]

I've been trying (and failing) to find an explanation for the focusing anomaly you experienced with the A7RII, putting it down to field curvature - exaggerated by the very short distance from sensor to test chart with such an ultra-wide-angle lens - and to the higher resolving power of the 42MP sensor or perhaps to some slight inaccuracy in the adapter's construction. Out of interest, were you using a Metabones, an MC-11, Commlite or another adapter? I'm sure you were only focusing manually, with OSS switched off... By the way, if you plan to test more Sigma lenses then it might be worth investing in a £39 Sigma Dock. I was hoping that Roger Cicala's review (www.lensrentals.com/blog/2017/07/sharpness-tests-of-the-sigma-14mm-f1-8-dg-hsm-art/) might throw some light on this but he only briefly mentions field curvature. You may be also interested to know that Lens Rentals (in the USA) appears to be offering the Sony E mount version for hire soon - in a couple of day's time if you take their hire page literally! www.lensrentals.com/rent/sigma-14mm-f1.8-dg-hsm-art-for-sony-e

[@TylerThomas]

If the blurry corners were due to an adapter, it would seem like not all 4 corners would be off in the way. I think that's why he stressed "all four" because if the lens was tilted at an angle the blurring wouldn't be evenly in all four corners. I wish he would've tested if the corners were also blurry at longer distances. It kinda seemed like he found a happy medium where the center and the corners were decently sharp... This video has had me trying to research field curvature for a couple hours and I'm just getting a mixed bag of results. If you know of any good articles beyond what you already listed, let us know!

[@ogamov]

Sharper than Jordan Peterson OMG )) you nailed it with this one !! :)

[@TheLordinio]

is it possible that the field curvature comes from the thick filter stack on the A7Rii's sensor?

[@claudeganter3911]

Yes this is probably the correct explanation.

[@alexabadi7458]

I have the 135mm f/1.8 (Nikon version) and I love the built quality and the lens performances.

[@samsen201]

Excellent review as always. I can't wait to see what gurus of astrophotography have to show us and how they can capture milky way with this. Yet at this price, despite all the merits, I don't have this lens in my wish list as first of all, my Samyang / Rokinon 14mm 2.8 is more that what I can dream about (I have three copies of this lens). Then, and if I was in market for wide / ultra wide, fast lens, my first choice probably would be this but at 1/4 the price, with only 10 percent or less, lose in quality, my choice would be Venus optical Laowa 15mm F/4 and not F/2 that you mentioned at 10:46 minute. Anyways excellent job and thanks for your great work in this review. You are a priceless source of truly unbiased information with right projection of scientific data (That really matters to user), at best. A very unique and rarity on KZbin.

[@zvkvhs3818]

I recently used this lens and focusing with great ambient light it had major issues. I have the 1.4 in route and I hope they’ve fixed some of those problems.

[@TheGKFront]

Hi Chris! How are the Sigmas behaving with the R5-C? I have the tamron 15-30 which I will be returning , as the AF and stabilization won't work in Video mode, and I only discovered about this after seeing it doesn't work and googling the issue.. quite a few complain in forums but Tamron says 'it doesn't test it's lenses with EOS cinema cameras' as the weird excuse to why it doesn't fix this.

[@rdgronconi]

Hi Christopher! Thank you for your reviews, I´ve been watching some of them on my quest for a good wide lens for Canon EF mount (I have a 6D). In general, what would you spend your money on? 1) Sigma Art 14mm f/1.8; 2) Sigma Art 14-24 f/2.8 or; 3) Sigma Art 12-24 f/4? Or any other option?

[@UnknownMeAsif]

in your view between canon 14mm mk ii vs sigma 14mm art which lens is better and why. Thanks

[@dallatorretdu]

Maybe the adapter is a little bit skewed or tilted so one corner will be too far from focus and the other is too close. if you could inspect that.

[@loudandclearmedia]

Great review. I'm considering picking one of these up for architectural video with my RED Dragon-X 6k, which has a sensor with an approximate 1.25x crop (from 35mm) in 6K, making this ~18mm. I'm wondering about the barrel distortion, and if you have tried to correct it using premier's built in barrel distortion tool?

[@claudeganter3911]

Thank about your reviews. Much appreciated. About the curvature of field on Sony camera: While super wide angle lenses have huge depth of field on the subject side, the image plane on the sensor size is actually razor thin. Also if the lens is not a telecentric design, like it seems to be the case here, then rays arrive with an angle of incidence at corners. The optical path will then vary as a function of angle of incidence and glass thickness (stack) in front of sensor hence curving the image plane field. See for Brian Caldwell and Roger Cicala articles. I would suggest to test the lens on a Canon 5DS R which is probably closer to the intended design of the lens.

[@jefffenske1958]

So how do you explain this in practical terms?

[@claudeganter3911]

Well that was the simplest explanation I could figure out. Just kidding. Anyway, what that means is that when you "adapt" a lens on a Sony A7x camera - especially if it is a super-wide and even more so if it has a large aperture - you may get field curvature blurring the corners. The adapted lens and the camera stack are one unique optical system. To mitigate the problem, there is a company that sells 'thin' stack modification for Sony cameras. Just google 'kolari mod'. But it seems expensive and no warranty that it works perfectly for this case.

[@moritzio4.034]

But you had the EF version of the lens, there is also a Sony E mount available or am I wrong ?

Kudos for Jordan Peterson! Wide angles lenses have problem with thus. What adapter are you using? I checked on yt and most adapters do it pretty bad but from Metabines IV smart adapters (which I owe) have some velur insides that helps fight problems with edges sharpness at wide angles.

[@jefffenske1958]

Why do mirrorless adapters require more than air for lenses to work properly?

[@jefffenske1958]

I see. I thought "smart adapters" meant something else was going on besides just an anti-reflective coating.

Lovely review as always. Is this sharper still, than their 20mm f/1.4 (?) Art..?

[@christopherfrost]

Not sure, really - perhaps the 20mm lens is slightly sharper

[@juanmalbox]

When a lens gas floating elements the adapter can produce extremely big field curvature if the tolerances in flange distance are not the same as a normal canon EF mount

[@jefffenske1958]

Why?

[@shang-hsienyang1284]

What's the "George Peterson" reference? By the way, adapter reduces wide angle lens sharpness. My Sigma 20mm f/1.4 corners also look terrible if I focus on the center point. I often have to put it on a tripod to perform focus stacking..... so much for the IBIS feature that I can't take advantage of.

Adaptors always cause issues especially from one make to another. Many of your videos where you adapted to your apsc canon many had issues with the adaptor which you wouldn't have seen on a apsc without an adaptor.

[@purposefully.verbose]

for the price point, i think the Laowa 12mm f/2.8 distortion free lens is superior.

[@MickyMouseLimited]

Every time you use a converter or adapter you are introducing a chance of an error that was not originally taken in to account by the manufacture because the product was simply not intended for this use. Later trowing the product and manufacture under the buss buy testing it with adapters on camera that was intended for really shows nothing about the product it only shows that the user is ignoring the manufacture instruction and then is complaining about the final result. It is like buying shoes 2 size bigger filling them up with different insoles to compensate for the size differences and then complaining that the shoes are really not comfortable .

I think the effect is way to strong and it can't be a lens problem. This also would have rendered this lenses useless on a 50 megapixel 5Ds. It was one of the reasons for me picking up Fuji cameras rather than Sony since I do not have to think about adapter problems.
