Leica R 16mm lens, 3-cam version. Serial number: 3009430 I am selling this lens because it has been stored in a dry cabinet since I purchased it in like-new condition. It has never been used outdoors, only tested indoors. There is no dust, dirt, or clouding, and it is in very clean condition. The original lens case is also included (photos 7 and 8). This item is also listed on other sites, so it may be removed suddenly. Thank you. #Leica #Leica #16mm #3-cam #lens
