Nikon 80mm f4 Nikkor for Nikonos eye piece if you compare it toThe Nikon 80mm f4 is designed for use in or out of the water; it's only one of two Nikonos lenses that can do this (the other is the standard 35mm f2. 5.) In excellent condition, with clean glass. Cosmetic condition is excellent! Original box included. Please note: this lens is for the Nikonos underwater camera system, not the much more common (and terrestrial) Nikon F mount. It will not work on an F mount camera. Do not buy this for a Nikon F mount
