Released in 1981 as part of Pentax's compact 35mm SLR series, the Pentax MG embodied the industry's trend toward more compact and user-friendly cameras, inspired by the Olympus OM-1 in 1972. It succeeded the Pentax MV1, introducing enhancements like a shutter speed display in the viewfinder and a sleek chrome or black finish. The MG was designed as an aperture priority automatic camera, emphasizing simplicity for users seeking convenience. Its compact design, user-friendly features, and compatibility with the K bayonet mount for interchangeable lenses, including the SMC Pentax-M series, contributed to its popularity. The Pentax MG found favor among photographers looking for a reliable, compact SLR with modern features. Production concluded in 1984, marking the end of an era for this notable Pentax model.
