Another one of those almost impossible to find lenses for the NC series. I finally was able to get my hands on one, but it was unfortunately disfunctional. It was not possible to zoom the lens due to some very sticky material inside (looks like a plastic or rubber part melted or disolved). I spent many hours on cleaning the inside of the lens, and I was finally able to get it to work again. You can expect most samples of this lens will have this or a similar problem.
I took several test shots with this lens, and the optical quality is really excellent. I have a lens test from the German magazine “Color Foto” from 1/80 and this lens tested extremely well.
