What aperture were you using with the 50? At 1.4 the depth of field is very narrow. If taking a photo of a person focus on the eyes. at 1.4 the only thing in focus would be the eyes. In my opinion 1.4 is to narrow for my liking. Portraits should be at 2.8 - 4.0, group shots 4.0 - 11, Landscape should be done f/11 - 22. This is me now ... not every one will agree on my style of shooting, but I think most would agree. But actually the best way to learn is practice practice and practice. Ohh and congrates on the 60D, You'll love it.
Many thanks for the advice - this is exactly the type of info I need! Have to head out now but I'll check later to see what aperture the portrait setting used. Just learning about using the AV setting last night, haven't had the opportunity to put it into practice yet! Thanks again!
