I do loves me some shallow DOF. Every time I put on the 50mm f/1.4 I’m amazed at the quality and sharpness of the images (even wide-open). But it’s takes some fast focusing and a good idea of what you DO want to shoot to get things right. Attila recommended it to me, and I will recommend it to you. That or it’s cheaper but still very good cousin, the Canon 50mm f/1.8.
Obviously I need to hone my skills if I’m ever going to master use my “dream lens” the Canon 85mm f/1.2
Have you shot much with your 50mm 1.4 on your 7D? Mine looks great in the viewfinder but the focus ends up being just off a bit…I've not gone through the Micro AF adjustment but am thinking that I need to do that. You ever mess with the focus adjustment?
