Think this thread could be moved to f/stops so all AP members that don't look in Gear Talk learn something maybe (but then do those that look in Gear Talk look at f/stop? And do those that look in Gear Talk and f/stop have any idea on this subject? So maybe it should be in Photographic Help and Advice somewhere?)
