Pentax K2

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 for Zeiss in a joint venture never really to be developed. The two others were the KX and the KM. Along with these cameras, Pentax released a 26 Super-Multi-Coated (SMC) K mount lenses. The announcement of the K-mount cameras and lenses occurred at a large Pentax birthday celebration held at the Imperial Hotel in Tokyo, Japan.[1]
