Pentax K system

A 35mm full-frame SLR system, which was very popular at the time. Initially, it was an extensive line of manual focus film cameras and lenses, but since 1987 it includes autofocus models, and since 2016 - digital cameras. Unlike Canon, which abandoned the FD mount in favor of a fully electronic autofocus EF mount, Pentax chose not to create a new mount for autofocus lenses, but go along the path of modifying the existing one. The system currently includes one base digital SLR model and a meager set of lenses consisting of older designs updated to the modern HD coating, several models of the professional star series, and models created in collaboration with Tamron.
