Nippon Kogaku NIKON Nikkor-Q.C 13.5cm f/3.5 Lens Rangefinder RF Contax C-mount. It cones with the original OE rangefinder and carrying cases.

This is a C-mount specifically designed for Contax RF IIa and IIIa rangefinder cameras, not to be used on any Nikon cameras. This lens is in excellent + to near mint condition for both cosmetic and optical condition with both original front lens hood/cover and rear lens cap. It also comes with the OE leather carrying case in good condition. The rangefinder is in mint condition and it has adjustable parallax compensation.

According to my online search, Nikon S-mount wide angle lens can be used on either Nikon S-mount or Contax RF C-mount cameras but not with other longer focal lenses. People who had both Zeiss 135mm and this lens said they performed about equally (some said Nikon did better). I used it on a Contax IIa and IIIa.

I have many other Contax RF cameras and accessories listed, please check my other for sale items to see details.
