Do you typically need to calibrate your lenses on this body? Have you did so on 135L, and have you got good results from it both on full body horizontal, face and far (infinity focusing) @ F2?
I ask this as i do not believe it is possible to properly correct misalignment of mechanical parts in the body (bayonette, mirror, secondary mirror, AF sensor and imager sensor) by simply dialing-in some delta in AF sensor readout.
That's why you have to correct the sigmas with a dock at different distances, as well as to correct every single lens.
What sigma tried to do here is (i guess) they dialed in some kind of correction into their lenses, which is no-no. Maybe they did so to compensate for focusing mechanism ballistics, i don't know. What i know is, if the body is spot-on, there is no need for any kind of corrections for "dumb" lenses. And i have "dumb" body too (Kodak 14NX, nikon guy here). All i had to do is tune it mechanically, since then it is tack sharp, on any distance.

Canon and Nikon both recognise that mfa is often necessary for lenses due to manufacturing tolerances and the higher degree of scrutiny that images receive thanks to high mp bodies. They both recommend in documentation to set the mfa value for a lens at the focal length, focus distance and type of lighting you are most likely to be using the lens in.

It's not just a Sigma thing.

Sigma allows us to go one step further and fine tune a lens for many different focal lengths (four with their zoom lenses) and many different focus distances (four again). This is an improvement on the second rate, coarse adjustment available to us in Canon and Nikon cameras

Relax.

Reviews prior to release are great for generating interest but as this thread has shown they aren't of any real use for evaluating the lens. You need a larger pool of users than the chosen few to form a conclusion.

The SLR Lounge review not only included stellar images, it was the most comprehensive review of the 85mm Sigma Art lens to date. Needless to say, this lens is going to produce some incredible images.

I once attempted to own the 85mm 1.2L II, but I thought the lens was broken it focused so slowly (may have been, but my experience with 2 of them was years apart and I was never impressed). The CA handling is downright offensive too...I have a 135L to satisfy my bekeh needs!

My biggest concern moving on to a new 85mm is how it will handle Chromatic Aberration. This is a tremendous improvement over the Canon (no green fringe and reduced/controlled magenta) and enough to sell me again. LOL The author says it still suffers from CA, but neglected to provide readers the fact all autofocusing 85s on the market look bad in this department and this could be the best. I'd like to get mine in my hands, but I know I'll be seeing a good improvement... especially at 2.0-2.2 where the lens will live at until I need 1.4.

Amazon hasn't received its shipment in yet. I previously preordered mine very early with B&H along with a Canon 5D MkIV battery grip...and I didn't realize they weren't going to ship them until they could ship both. Then I switched to Amazon for one-day shipping being $6.99. I'm not too worried or bummed. I've waited almost 16 years to replace my Canon 85mm 1.8...what's a few more days?

I never found the 85L to be too slow. It kept up with basketball.

On my 135L I am at +2 AFMA with 99% of the shot in focus

On the Sigma, here is an example of 20% of extreme shots I got (focus point was on the cheek), 60% of the rest was still out of focus.

I just don't see the tackness... and I think it's their shutter. Most of the shots are around the 1/200 range. The one shot I see that is wide open that is 1/500 is this one:

https://www.dpreview.c​om …sample-gallery/0520541359 (external link)

But it's not tack sharp. I'm at work right now so I can't play with the RAW but I think this might be a SOOC JPG with sharpening at 0. The 5D4 JPG are fantastic but I've been shooting the JPG with the "Fine Detail" style so it's naturally sharpening the image.

ONE thing that impresses me is the CA control. There are some very tough scenes in there and it's not 100% CA free but holy poop it's controlling CA in my opinion VERY good for an 85mm prime lens!

The bokeh on all the shots looks fantastic even with this scene: https://www.dpreview.c​om …sample-gallery/4589586811 (external link)

That leaves bokeh background is typically very hard to control and are imho usually very busy yet the Sigma creams it away.

CHROME guys.... this is chrome..... VERY controlled CA. Just a smidge and I cannot see it until I blow it up and then it's very little.

The bokeh is excellent! I am so super pumped for tomorrow I may just take the day off so I can pace back and forth at my front door waiting for my delivery  :p

The 85L gets a bad rap for being too slow to focus but as you found out it depends on the situation. There are people using it successfully for sports as it focuses rather fast at moderate focus distances as I explain here: https://photography-on-the.net …showthread.php?​p=17893281 . The deliberate slow focus is only at focus distances of less than 8 feet which is required to accurately focus for portraits when using f/1.2.

OMG YES!!!!

You talk about getting upset... up till about 30 minutes ago the status has NEVER been updated for mine since friday as if it was stuck in KY. Oh h0h0 buddy is today going to be a SLOW day.

I am more pumped about this lens than I am about the 5D4 arriving.

Looking very good optically, but still there is quite amount of longitudal chromatic aberration present.. It might be pretty difficult to get rid of it.
Lateral CA is usually less problematic as it can be removed in lightroom as example.

Of course it's still there.... but have you compared it to any of the alternatives at this point? I'm not super keen on all the techy talk to the optics... but compared to the 1.2 or the canon 1.8 the CA is vastly improved.

People who have had this lens already says it's really good. I have the 35mm/50mm Sigma and the 135mm F2 from Canon, should I sell one for the 85? The 85 is worth 2 used 135mm f2.... :( decisions decisions

Kind of lenient on selling the 50mm but it's hard to find one that nails focus and this one nails focus when I really need it

have you calibrated yours with the dock?

I keep hearing all these stories of bad AF but then i find out they haven't calibrated them. The arts I have calibrated are rock solid.
