I am on the fence about what to buy next. I keep thinking I am eventually going to be going to full frame, but am shooting a 40d right now. Currently I have a 24-105L and a 50mm F1.8.
I am thinking of buying a 17-55 F2.8, an 85mm, or the 50mm F1.4. Any advice? This will be for mostly outdoor shooting (park settings,etc).
