The Nikon 35mm f2 Nikkor-O Auto is a compact lens- not much bigger than a standard 50mm- that provides a slightly wider field of view. Cosmetic condition is good, with some paint and finish wear; focusing is smooth, though light. Optics are free of hazing or fungus, but there is internal dust. This pre-AI lens has been converted (with an original Nikon part) to AI, so it can be used on most modern Nikon F mount cameras.
