The Pentax P50 (P5 in the US) is a manual focus SLR utilizing lenses with the KA mount. It was first issued in 1986, and was followed by the P3/30 in 1985. It marked the beginning of the P-series of cameras with plastic bodies and was the first Pentax camera with 2 program modes and a large LCD on top.

The standard lens is a 50 mm f/1.7.

The camera has five exposure modes. Settings are displayed in an LCD screen to the right of the prism, and selected by navigating the menu with 'Up' and 'Down' buttons beside the display. The major modes are:

  • Programmed AE with a bias toward fast shutter speed
  • Programmed AE biased toward small aperture
  • Aperture priority AE
  • Metered manual exposure
  • Programmed mode for dedicated auto flash

The shutter is a vertical-travel focal plane shutter, with speeds from 1 second to 1/1000 second, plus 'B'. Flash synchronisation is at 1/100 second; the camera is compatible with some dedicated Pentax flashes.

The camera reads DX codes on film, and has no other ISO setting control. If film without a DX code is loaded, the film speed is set to ISO 100.

The camera requires two 1.5V LR44 alkaline or SR44 silver oxide batteries.
