i understand that lens with f2.8 are the better and more expensive 1.. for example 2470. 70200. f2.8
i know the wide aperture will be very useful for night shooting and with it.. enable us to use a faster shutter speed.
However..im confused.. after i read the photography books.. in daylight..nobody shoots at f2.8 even they uses those lens.. they probably shoot at 5.6 or higher n up to 22 for landscapes. Err.. so what happen if i shoot at f2.8 in daylight? n why people generally dont use it.
(isit because during the day.. its too bright.. to use wide aperture? even if im on aperture priority mode it will turn overexposed?)
isit something to do with "sweet spot" i read about?
