Yashica Bay 1 Yashinon Telephoto brand_Photographer's Formulary which is bigger than mostGive your Yashica Mat (or any other camera with a Bay 1 filter mount) a bit of extra telephoto reach with this Yashinon auxiliary lens set. It's not telephoto telephoto, mind you, but it'll give you a bit more of a portrait lens field of view. Cosmetic condition is good, with some finish wear; optics are clean. Includes attachments for taking and viewing lenses.
