The Yashica Penta J3 is a SLR with interchangeable M42 screw mount lenses.
The Yashica J3 was offered with a 50mm F/2 Auto Yashinon lens that had a M42 screw thread. The camera has an internal exposure meter that couples to the shutter speed dial but not the aperture so only had closed aperture metering.
