Asahi Takumar 35mm f4 mount This specialized cable release fitsThe Asahi Takumar 35mm f4 is a very early M42 lens, with a manual aperture, not even a preset or one of the later manual reset autodiaphragms. How early is it? Glad you asked: it's Asahi's first 35mm lens, ever. In excellent cosmetic condition, with light finish wear. Glass is clean, with light dust; focusing is somewhat stiff, though usable. A rare one in pretty solid shape.
