The Leica M is a digital full-frame 35 mm rangefinder camera. It was introduced by Leica Camera AG in September 2012, and is the successor to the Leica M9 range of cameras. The M uses a 24-megapixel image sensor. The camera is the first M model to feature movie recording, and the first to have Live View—which allows the scene, as seen through the lens, to be composed. The M is compatible with almost all M mount lenses and most R mount lenses (via an adapter). All Leica M cameras are handmade in Portugal and Germany.
The M supports most M-mount lenses, and with an optional R-Adapter, the camera can use almost all Leica R-mount lenses. Live View allows owners of R-lenses to use an optional electronic viewfinder.
