Nikon 50mm f4 EL-NIkkor brand_Tetenal TheCarl Zeiss Sonnar 50mm f2The Nikon 50mm f4 EL Nikkor is a lens designed for use on enlargers with 39mm lens threads. This lens will mount to Leica Thread Mount cameras (which are also 39mm) but will not work at all, not even a little bit. Don't buy this for your camera: it's for enlargers. It's clean, and in excellent condition, with original box and case.
