OK, I've been trying to shoot some photos using the "creative Zone". I have been using the automatic zone for so long, that this is all new for me. I shot about 100 different things using the side lighting. This is the best I could get. I found that many of the shots I took using the AV setting were not as crisp as I am used to getting. I would love some suggestions from you pros. I do not have a fixed lens, but I tried to keep my 28-90mm at about 50mm.

settings: Aperture Priority. Shutter speed gets set automatically at 1/100 on this shot (not sure why it sets at these settings?) f/stop f/4.5, ISO 100, focal length 52m.
