K1000 is a 35mm film SLR camera made by Pentax and produced between 1976–97. Its design descends from the original Spotmatic series of screw-mount SLRs introduced in the 1960s.
An affordable camera for the amateur photographer, it was a fully mechanical, manual camera designed without any program modes. It survived much longer than originally intended and became the archetypal “student’s camera.” The K1000 was equipped with all features required for manual photography: a TTL metering system, wide-ranging shutter speeds from 1/1000 to 1 s, and the ability to use all the available K-mount lenses made by Pentax and licensees such as Ricoh and Cosina. The K1000 omitted some features found on more advanced models, such as depth-of-field preview, self-timer, and separate meter on/off switch.
