Front anamorphic attachment 35NAS4-1 for Konvas

Complete set consists of 2 lenses and the front anamorphic attachment for them. There is the anamorphic attachment only. Quite used condition. No fungus, but there are some tiny cleaning marks. Also, there are few scratches of the front element, unfortunately (most significant is showed at the picture below.

As far as I know, even much worse scratches and chips are being filled by black paint to prevent a light reflections, and such lenses are still in use even at studios. But  I can't suggest if for a professional job, though it is still very suitable piece for an amateur willing to try this type of attachment for his project.

Relative Aperture - f/2.5;
Focus Range: 1 m to inf
