I pre-orderd at The Camera Store in Calgary back in early May. I just got a call yesterday and picked it up. So far so good, mostly the same as everyone else
It worked perfectly straight out of the box, and I am loving the combination of extreme sharpness with extreme bokeh! I also love how close it focuses, because I'm almost always at the MFD of my 85mm and wishing it would get closer (p.s. anyone want to buy a sigma 85mm?)
I have noticed that the focus points on the outer edges of 5D MkIII are not very consistent... Sometimes they nail it, but other times they dont. If I must use the outer points I'll likely take 3-4 pictures to make sure I get the focus I want. Not ideal, but I honestly haven't had and lens faster than f/2.8 getting accurate results on the outer focus points. I am only using the cross type points.
There are so many threads about this lens, so I don't know where to post but I'll update if it goes crazy like Viggo's first one.
