I am just getting into portrait, street shooting and using Canon and a full frame with a 50mm 1.2. You only have one chance at a shot like this on the street. I met this graffiti artist yesterday and lets just say he wasn't going to stand still for a portrait for more than one shot. example of the AF, especially on a 50 1.2 which has been historically plagued by AF issues. Also detail and FF DOF. Let me know what you think...
