Huh.  I just got my Canon 50mm 1.4 and took it out the box and it has a pinch cap. Didn't know they were doing that.

Autofocus performance is in general a mysterious and frustrating topic.  I have had a Sigma 50mm F/1.4 for around 3-4 years.  I got it to use on my 5D classic, but it front focussed enough to be annoying and there is no micro-adjust on that body.  (Canon calibrated the body for me shortly after I bought it used.)  I managed to get some use out of it for portraits by focusing on the subjects ear, then the eyes would be sharp!  ::)

When I got my 5D III last Fall, the Sigma worked great with it, needing very little MFA.  I use it a lot now for full body portraits at about F/2.0 to F2.8 to get just the right background blur.  Sorry I don't have any acceptable images to post right now, most of my work is not appropriate for this site.  ;)
Current bodies:  5D3, 7D, 550D, S100
Favorite lenses: 135 f/2.0 L, 85 f/1.8 200 f/2.8 L, 50 f1.4 Sigma, 40mm pancake, 24-105 L.

I wonder if I could get inspired by this and actually get some usage out of my lens. "Please, lay down and spread your legs so that I have something to focus on to get your eyes sharp."  ::)
