Novoflex 400mm f5.6 Noflexar / LINSE-400 + Follow Focus Pistol Grip (PIGRIFF)

There's oil on the aperture blades that makes the aperture sticky and slow. It has minor fungus and haze that do not affect image quality. The fungus has been UV-treated to neutralize it and prevent its spread. It’s a bit worn externally, but works well otherwise. Comes with a Nikon F adapter.
