The Pentax K2 is a 35mm SLR camera introduced by Pentax in 1975. It was the flagship camera of a trio of that year featuring the new K lens mount developed in conjunction with Zeiss. Taking advantage of new technical possibilities, the camera has full aperture TTL exposure metering, with a black indicator needle visible to the right in the viewfinder.
The K2 has aperture priority automatic exposure, selected on the shutter speed dial. The camera selects the proper shutter speed between 1/1000 and 8 seconds when the shutter release is depressed. Other notable features of the K2 are the mirror lockup, and that shutter speeds from 1/125 to 1/1000 second and 'B' work without battery power. Despite its short production run, the K2 set the stage for fine Pentax cameras to follow.
