The Leica M4 is a 35 mm camera by Leica Camera AG.
Leica M4
The M4 started production in November 1966, as the direct successor of the M3 and M2, featuring framelines for 35 mm, 50 mm, 90 mm and 135 mm lenses in a 0.72 magnification viewfinder. It has the frame counter of the M3, with automatic reset after reloading.
Three ergonomic modifications were introduced in the M4:
- a different, angled film advance lever, as well as slightly different rewind, self-timer and frame selection levers
- a crank for rewinding the film, that replaced the telescopic knob of the M3
- a faster loading system that does not need a removable spool
Production of the Leica M4 ceased in 1975.
Leica MDa
A scientific version without a viewfinder was made as Leica MDa (similar to the Leica M1).
Leica M4-2, Leica M4-P
Production of the M4 stopped briefly in 1972. Its successor, the M5 had been introduced in 1971. However, the relatively bulky and expensive M5 met with a cool reception, and sales did not live up to Leica's expectations. Production of the M4 was therefore restarted quickly until 1975. In the year 1975, a special edition was made for Leica's 50th Anniversary, and in 1977 the company launched the updated M4-2, which was based on the M4's body, but with a streamlined production process that reduced manufacturing cost. The M4-2 added a hot shoe and motor drive compatibility as standard, but removed the self-timer.
The M4-2 was followed in 1981 by the M4-P, which added framelines for 28 mm and 75 mm lenses. The range continued with the Leica M6 in 1984, which was essentially an M4-P with through-the-lens (TTL) light metering. The M6 finally ceased production in 1998, although Leica released a special edition with a high-magnification finder in 1998.[1]
