previous digital cameras I've owned (on my third one; they live a rough life with me at my dog park) but the shutter lag still gets me. Canon sx40hs point and shoot. I see lots of great shots that I just can't capture because the moment has come and gone before I can get a shot off. So I shoot lots of pictures and even then, the ones that are captured at the right moment very frequently then have some technical issue such as focus and depth of field, as in this shot. As for composition, on still shots I worry about that, but most shots I'm happy just to get the subject in the frame and crop as needed.
