It has stunning image quality on a full frame camera, but wide open the depth of field is so shallow that you can do a face with only part of it in focus but one eye super sharp. I found it quite a difficult lens to get used to.
Mine is the cheaper f/1.8 EF, but I know what you mean. That's really handy for exact focussing though. I run Magic Lantern, 3rd party camera firmware in the 6D, which lets me have focus peaking on the back screen or the HDMI output - the faster the lens the better it works.
Irony this last week: the Domestic Controller wanted a new passport photo, so I got out the 85mm, and took the pic at f/2.2 - pin sharp, can see every hair, background nicely bland and out of focus, etc. The Passport Office's on-line app initially rejected the image as being "blurry". I'd given her the jpeg as she was in a rush, so dropped the raw file into AfterShot and bumped the contrast and brightness up a bit, and the app was perfectly happy.
The Passport Office instructions say not to post-process the image in any way.

PS: my Canon 85 vignettes nastily. It's OK for portraiture, but very noticeable on other subjects (and the plain light-blue background to her passport photo). I inherited it recently, and I still enjoy using it, but the penny has now dropped that it was probably designed for an APS camera body (dad had a 350D).
