could some one please expain this to me im aware the full sensor isnt used to take the picture but im in need of understanding how this effects the focal range of a lens.
ie after looking at lenses even though some are digital the lens is say 70 - 300 but the seller will state effective range on a dslr is 105 - 450 (numbers not exact but approx)
