This is a great little read from BHPHOTOVIDEO.com 'Inisghts'. You've probably read a few times many professionals might shoot at F/5.6 to F/8.0 but this could be simply because they are using F/2.8 lenses. There's a difference between getting everything in focus as to what's really the sharpest setting on your lens. It might be a bit confusing reading this here, so take the jump over to the Inisights article and try some of the suggestions against your own lenses.
