We purchased the Kodak DX6490 about 3 weeks ago and I can get pretty good shots with it, but my wife gets nothing but blurry shots. I have watched her and tried to help her, but she still gets only about 2 clean shots out of 20. Does anyone have any thoughts or suggestions? It seems that the camera is constantly searching and even when you press the button half way down it takes a little while to set the focus.
