The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 x 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch.
M42 thread mount cameras first became well known under the Praktica brand, and thus the M42 mount is known as the Praktica thread mount. Since there were no proprietary elements to the M42 mount, many other manufacturers used it; this has led to it being called the Universal thread mount or Universal screw mount by many.
The M42 mount was popularized in the United States by Pentax; thus, it is also known as the Pentax thread mount, despite the fact that Pentax did not originate it.
The Pentax K-mount, sometimes referred to as the "PK-mount", is a lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras.
It was created by Pentax in 1975, and has been used by all Pentax 35 mm and digital SLRs since; it is also used by the Pentax K-01, a mirrorless interchangeable-lens camera introduced in 2012.
A number of other manufacturers have also produced many K-mount lenses and K-mount cameras.
