ISCO-Gattingen Westanar 50mm f/2.8-16.0

Unusual lens with automatic-diaphragm, actuated by pressing the knob, which will trip the shutter on some earlier Praktica and Edixa cameras as well. This system is quite wellknown from the automatic lenses for the Ihagee Exa and Exakta. The position of the M42 screw mount can be regulated by loosing 6 tiny screws, holding the M42 ring in position. Allows to adapt the lens to the right position for the used camera.
