This old lens is in very bad shape, in terms of optics. The rear element's coating has sort of "disintegrated" and becomes a foggy mess. The only sharp area of this lens is the center. I can not make the edges sharp on a full frame camera, even significantly stopped down. But, I kinda like the way the pictures were created. I am sure this would be a nice portrait lens.

This lens was originally in Arriflex mount converted to Nikon mount.
