When talking about M42 bodies and lenses, people are accustomed to adding the name Pentax. It was the 1964 Pentax SP series camera that made the M42 screw-mount SLR cameras begin to gain popularity, and soon, Pentax became synonymous with M42 screw-mount cameras. However, the name "M42×1" actually originated from Bertel and Contax.
