Re: Aperture on Tele-Xenar 4/135 does not open all the way - why?

DKL mount lenses have two aperture levers (one isn't so obviously visible). One sets the aperture and one opens and closes the diaphragm when the shutter is released (when used on its original bodies). It could be that the aperture setting one is set to closed down a bit.
