The Leica M4 is a 35mm rangefinder that succeeded the M3 and M2 cameras. It was introduced in 1966 and, for the most part, had a production run through 1975 - with one brief halt in production when the M5 was introduced. The M4 is considered by many to be the best camera ever made by Leica. The M4 builds upon everything good about the M3 and tweaks a few things to make it even better. Notably, the M4 incorporates four sets of framelines: 35mm, 50mm, 90mm, and 135mm. These lines automatically show up in the viewfinder when the corresponding lens is attached. Alternatively, they can be triggered manually via a lever on the front of the body, to allow the photographer to preview a scene prior to mounting the lens. The M4 also introduced the canted rewind crank, which replaced the earlier rewind knobs of the M3 and M2, making the process of rewinding film faster and easier. The M4 also uses a three-pronged, non-removable take-up spool inside the camera body, which greatly sped up the loading process.
The M4 uses the Leica M-mount lenses. This camera is all mechanical and requires no battery. There is no meter and the exposure is set in a purely manual fashion.
