ETTL, 45* with a stofen diffuser.
Ah, yeah, the Tamron hunts a little, not as much as the canon 18-55 kit lens though. The 10-22 is faster in focusing though, you're right. f/4-5.6 is probably the best for single or two person shots, I go to f/8-11 if I shoot a group with multiple levels of people. I also always try to get two shots at lease with different shutter speeds and apeture to make sure that I get "the shot".
