@Sharra: I always keep my autofocus setting on One Shot, unless I’m dealing with moving subjects, so that I can lock it on their eyes and then recompose. You’re right about calibration. However, according to another photographer I know, the crop bodies don’t work with lens calibration? I could be way off on that and misinterpreted him. I think things will get so much better when I get a 5D Mark II. Until then, I’ll try not to pull out my hair 🙂 And of course, work on fine-tuning my skills.
