I got this lens, can't be happier for the past week + I've been using it in doors, out doors and around town, portraits or scenery it works perfect the way I expect it to. It has been glued to my 5DII and though weighty, it's balanced very well with the body, no problem for me. Bokeh? Times were it gets interesting, but I like interesting, and it's better than my Canon 50mm 1.4 wide open at least. Sharp sharp sharp all across, I never was big on how sharp a lens was until I started shooting this, oh man, "why even stop down?" I thought, though shallow isn't everything of course

AF, no problem with the lens, just my 5DII not locking on where there isn't much light or contrast, and so far I havne't gotten a reason to AFMA it, I should try anyways, but haven't had any problems yet.
Now, worth the money? Well, I have no regrets, but I would really say $650~700 would be the killer price.
