Leica Hektor 13.5cm f4.5 LTM Lens Head Only (No Barrel) -Parts, Bad Aperture-
This is the lens head for the Hektor 13.5cm f4.5 telephoto lens with the glass. The barrel is not included.
It is for parts only. The aperture does not work, one of the blades is out of sync and it prevents the aperture from opening and closing properly. There is some minor coating wear on an inner element that I can only see with a flashlight.
