The Pentax PC35 AF was the first 35mm compact camera with autofocus from Pentax released in about 1982. Its name led to a whole range of Pentax PC cameras.
The PC35AF winder accessory offers motorized film advance and a better grip. It needs to be switched on independently of the camera and requires its own batteries. A coin can be used to attach the winder to the body. Once installed, the film advance thumb wheel of the body is covered. This cover can be slid open and the thumb wheel can be used when initially loading film. Close the film back, slide close the cover of the wheel and power on the winder to automatically advance the film to the first frame.
