Hi all
had today a play with my old OM4 film camera and the only zoom i had for it, the Zuiko 70-210mm, and notieced that when i zoom in or out the focus do not change, unlike both digital zooms i use now the 70-300mm Zuiko and the 50-500mm Sigma.
please don't laugh at me if it sound silly, but can anyone explain why, is it something must be for digital or AF lenses.
thanks so much.
