Heya, do you have the Canon 50L? If so, I'm eyeing this lens, and curious about your experience with it. I realize shooting at f/1.2 creates some challenges (I already have the 85L)... but what other things have you noticed about this lens? Where is it strong? Where is it weak? I know when it first came out, there was a huge uproar over the inherent focus shift at short distances when stopping down... is this an issue that has affected your photography with this lens? How do you work around it? I imagine it's great for portraits but can it also be used for street photography or general snap shots or even product type photography? What do you use it for? Thanks for sharing!
