[QUOTE="WayneF, post: 233250, member: 12496"] [b]Re: Sharpest Aperature[/b] Lenses vary, some are f/1.4 lenses and some are f/5.6.... A rule of thumb is that stopped down 2 or 3 stops from maximum aperture is about the sharpest. For normal lenses, this is often around f/5.6, or maybe f/8. Stopping down more gives greater depth of field, but suffers from diffraction, more the more you stop down (so it is a trade off, depending on your goals). Landscapes may need more depth of field.
