Followed by Leica Luxur and Leica Compur (a total of 60,586 of the Leica I, Luxur, and Compur models were made). Interchangeable lenses for these were introduced in 1930. Leica Standard: 1932. The first Leica camera was designed with a film-to-lens flange distance of 28.8 millimeters. Leica II: 1932. The first Leica camera with a rangefinder.
In 1930, the Leica I Schraubgewinde was first produced. It had an exchangeable lens system based on a 39mm diameter screw thread, often referred to as the Leica Thread Mount or LTM. In addition to the 50 mm normal lens, a 35 mm wide angle and a 135 mm telephoto lens were initially available.
The Hektor is a photographic lens design manufactured by Leica Camera. [1] The first "fast" lens available for the Leica I(A) was the Hektor 50mm f/2,5. Later, the design was adapted for use as a long portrait lens, available first in a 73mm f/1.9 and 135mm f/4,5 screw-mount version and later in a 125mm f/2,5 bayonet-mount version.

The Summarit was initially introduced as Leica's fastest lens in 1949 with a maximum aperture of f/1.5. Since then, the Noctilux and Summilux named lenses have superseded this old aperture. [1] On 3 August 2007 Leica revived the name and announced a series of less expensive lenses, the Summarit-M.
The normal "full-stop" f-number scale for modern lenses is as follows: 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, but many lenses also allow setting it to half-stop or third-stop increments. A "slow" lens (one that is not capable of passing a lot of light through) might have a maximum aperture from 5.6 to 11, while a "fast" lens (one that can ...
The M39 lens mount is a screw thread mounting system for attaching lenses to 35 mm cameras, primarily rangefinder (RF) Leicas. It is also the most common mount for Photographic enlarger lenses. True Leica Thread-Mount (LTM) is 39 mm in diameter and has a thread of 26 turns-per-inch or threads-per-inch (tpi) (approximately 0.977 mm pitch) of ...
