5cm(50mm) Chiyoko Super Rokkor Lens

This is a 35mm rangefinder with interchangeable lenses. One of my best finds - I've seen it for over 200 bucks on E-Bay - I paid $30 at the thrift.

An accessory selenium meter fits into the flash shoe and couples with the shutter wheel on the top of the camera. This provides metered-manual exposure control(the first Japanese camera to have this feature). You dial in the film speed into the meter and then select the f-stop on the lens. Then, on the meter, you match the needle to the same f-stop and the correct shutter speed is "automatically" selected.
