Hi i've been reading from the net and some treads in this forum but i still cant understand whats the len's aperture purpose? what does it do?
Take for example the 50mm f1.8, i understand that aperture 1.8 means the hole is big. I read about it affecting the shutter speed and the dof too.
Any one can explain to me? Really very confuse over this.
