After 4 years of non-use I'm resurrecting my Minolta Maxxum film SLR and noticed a difference between my Minolta lenses and my Canon lenses. When the Canons are off the body the aperture is wide open, but when the Minoltas are off the body they are totally stopped down. These are Minolta Maxxum autofocus lenses. I assume it's just a difference between the manufacturers since all 3 of my Minoltas are stopped down when off the camera. Or do all 3 of my lenses have stuck aperture blades? Greg
