I tried out my old Sonnar 4/135 today. Note the Auto-Aperture button on the left side of the lens. With this lens I can pre-set the aperture and then, just before I take the picture, I simply press that button with my left hand and the aperture closes down to the pre-set value. I believe this design feature is unique to the Exakta and Topcon lenses.

Wide Open
