Threaded connection mount M39 lens and camera with 39 mm thread diameter and thread pitch of 1 mm. Used in photographic equipment to the Soviet 1930s. Connecting thread camera «Leica» was to inch increments - 26 threads per inch (M39 × 26tpi), that in terms of the metric system was 0.9769 mm.
Working distance 45.2 mm. The standard for SLR cameras. SLR cameras, CMH issued before 1967, had a threaded connection mount M39 lens, which came with a rangefinder cameras such as "Vigilant." Was increased working distance to accommodate the rotating mirror inside the camera. However, the diameter of the thread remains the same to reduce production costs and time required to create new lenses. The presence of the same thread with different operating segments of confusing consumers. In addition, the proliferation of thread M42 × 1 had to produce cameras with both types of threads, which led to an increase in production costs. In the future mount M39 × 1 / 45, 2 was replaced with M42 × 1 / 45, 5 (first introduced on the production model, "Zenit-E" from 1967).
The set of extension tubes to mount M39h1 production "FED" included an extension ring of thickness 16.4 mm, enables the camera lens "Zenit-3M" on rangefinder cameras "FED" and "Zorki"
