Nikon 80mm f4 Nikkor for Nikonos brand_Calypso 1) for A36 slip-on mountThe 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. 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 camera because it does not fit and will not work.
