The Pentax MG was an aperture priority automatic camera, with an electronic focal plane shutter from 1s to 1/1000, synchronized at 1/100. The shutter curtains were metal and had a vertical movement. There was no shutter dial, and the camera could not be used in manual mode, except for B and 1/100 exposures. The exposure meter was of the standard TTL open aperture center weighted type. It was activated by a slight pressure on the release button.

The Pentax MG had a 0.87x viewfinder, covering 92% of the field. The finder screen was fixed, with a split image and a microprism ring in the center. The shutter speed chosen by the camera was displayed in the finder, the aperture was not.

There was a self-timer and a hot shoe on the top of the prism with an additional contact for dedicated Pentax flash units. The selector around the release button had three positions: Auto, 100X (1/100, X sync) and B. The Pentax MG could attach the external Winder ME (1.5 i/s) or the later Winder ME II (2i/s). The Pentax MG could use the Dial Data ME databack with an adaptor to slide in the hot shoe, or it could make direct use of the Digital Data M databack.

The lenses were interchangeable with the K bayonet mount. Together with the M series was introduced the SMC Pentax-M series of compact lenses.

Production stopped in 1984.
