| Then: 1) Clean the lens. 2) Try using a higher shutter speed. It could just be you shaking. 3) I don't trust auto-focus unless it's digital. Use your eye. 4) The lower the Fstop the less depth of field in focus. If you want really sharp images? Use a high Fstop and a slow shutter speed with a tripod. If it's a film camera: Depending on wether you want high contrast or finer grain. (finer grain= equals sharper the enlargement) I'd prefere a slow speed film (200-100iso), with a high fstop and a SLOW shutter speed for deep reflections at a distance. But for higheer contrast i wouldn't go any higher than 400 iso as by then your grain gets to a rediculus size.
