Got a new toy the other day....here are some first impression shots. I will say that this is a great lens but it is extremely hard to shoot wide open. Check out the screen in the second photo to see how paper-thin the depth of field is on this lens (and these were not even shot at 1.4!)
I found this cool technique called HDR and a freeware program called qtpfsgui that helps you to do it. Hopefully I'll get better at this as time goes on.
