After taking the picture when I go into the image playback mode, the picture usually looks out of focus and generally of poor quality. However, if I zoom just a bit it becomes sharp and beautiful like the image during "auto review" right after I take the picture. It's hard for me to know if I got the picture I wanted if I just look at the playback picture. Does anyone know the reason for this? It's almost like the initial playback image is a low quality thumbnail or something until you zoom in.
