Aperture
OK, on all lenses we get the aperture (ex : F4-5,6) value of this lens. What I wanna know, is what does the aperture change? I know it means the opening of the diaphragm, but is a low aperture good or bad, and what kind of aperture should we except from a good pair of tele and macro lenses?
