Common Soviet 16mm & 35mm Motion Picture Lens Mounts

Lens mounts for the most common Soviet Era 16mm and 35mm Motion Picture Cameras

Krasnogorsk K3

The most common types of Soviet Era 16mm and 35mm motion picture cameras are the Krasnogorsk K-3, a spring wound 100ft load 16mm camera, the Kinor 16mm, with magazines and electric drive, the Konvas silver models, which may have hand crank options, the rarely seen spring motors, and various electric drive options, the 1M and 7M versions and the Konvas 2M and 8M versions, both sharing interchangeable magazines and electric drive options, and the Kinor 35S and 35N, also known as the 35C and 35H series cameras, self blimped synch cameras with a wide range of options and updates

The Krasnogorsk K3 is M42-1 [or M42 mount, which is a standard 42mm thread], and can use the 42mm Pentax or Zenit 35 SLR thread mount lenses [among many others. Note: A few were made with a bayonet-style mount; this mount is notably different, as it has two small knobs on the camera body's mount that turn clockwise to release the lens].

The Kinor 16 mount has lugs and a smaller deep round section on the rear with a short backfocal length.

The "OST18" (commonly referred to as OCT18) mount does not have bayonet lugs on it. It was only for the silver Konvas (Automat) and Konvas 1M and 7M series cameras.

The OST19 (commonly referred to as OCT19) mount is much larger than the previous mounts, has a longer backfocal, and comes in three versions, the early 2M, the "reinforced 2M" mount, and the 2M and Kinor 35S mount, which has less back room than the earlier versions to clear the mirror of the Kinor 35mm cameras.

The early 2M mount allows larger side to side projection of the rear materials than later versions.

The reinforced 2M allows heavier lenses and more solid locking than the early version, and prevents that lens from being mountd on the later Kinor bodies.

The 2M and Kinor 35S mount was also used for the the Kinor 35N as well as fitting all previous 2M bodies.

The Rodina, TEMP, and other Soviet era cameras have their own mounts, too. Those cameras are not commonly seen now. Descriptions will eventually be provided of the Rodina, TEMP, and other mounts, like the Filmo copy mount, and how to determine what the unknown and unseen versions are. BTW, there are a number of BNCR mount Soviet Era lenses. It seems they sold them in Europe.
