Me too on a Nikon 7100. Recently calibrated. Superb. However, the 18-35 art is not a happy camper on D500.

Is that a good point or a bad point? What colour casts are you getting with both lenses?

I purchased the Samyang 85mm for my Canon....tho its a manual focus lens.....very sharp. Ck out you tube reviews.....cost effective....

i had the Sigma Art 85mm f1.4 lens in Canon EF mount, used on my Sony A7RII with the MC-11 adapter. The image quality is outstanding, as good or better than the top Sony and Canon equivalents. You won't go wrong with it. It is big, but solidly built, and should last a lifetime of great images. Cheers

I purchased the Opetka 85mm 1.8 (same lens as Samyang) made in Korea ~3yrs ago. It is very sharp but must use a tripod most of the time. The thing is: it is totally manual (no electrical conections). I think it would make a great portrait lens. I don't (so far) succeed in doing shots very well from 10 yds. to infinity with this lens unless I use a tripod! The cost was less than $100. I use this lens on my T1i Canon camera.

Then I bought the Yongnuo 100mm f/2 prime made in China. I have collected about 10 or more lenses and really don't have any favorite lens although I tend to keep the Canon 28-105mm f/3.5-4.5 II made in Japan zoom lens on my T1i (the newer versions of this lens are inferior to this one). I love my camera and it's lenses!

Then I ask myself when I see all the upgrades of the Rebel line of cameras, why should I want these upgrades when I have not totally mastered the T1i? There is plenty of room to develop my skills and knowledge on this exquisit camera (I bought another one just in case this one develops a fatal flaw) and the more I take photos with it the more I like my camera -- isn't that something at my old age of almost 87?

What's the lens?

Note; If you get an Art lens get the USB Dock. It is the best way to upgrade firmware and to take advantage of customization available for Sigma's Global line (which includes the Art line) of lenses

I see this comment all the time about the Sigma dock and it's in their ads. But I've never asked the question until now: why would you need to update firmware for a lens? I figure that once you dial in focus, it's set. The reason I ask is because I've had the Sigma 50mm f/1.4 for about 4-5 years and never have seen the need to update the firmware. Also, since registering this lens with Sigma, I've never heard anything back about an update. Am I missing something with my lens? Just curious

Today's lenses are largely electronic. The USB Dock allows you to adjust operating parameters of your lenses. For instance it allows in micro adjustments on zoom lenses that are considerably more detailed than in camera micro adjustments. Also, again for zoom lenses with customization switches, you can set custom focus distances to reduce focus hunting. This is particularly valuable to wildlife photographers.

Mercy, that's a lot of updates. I never noticed any of these aberrations in my images, but then again, I'm not a photography judge either.
