|Leica M9, black|
On September 9 2009, Leica presented the M9, the first full-frame digital rangefinder camera. It features an 18 megapixel Kodak CCD sensor and accepts most Leica M lenses made since 1954. The M9 is Leica's second generation digital rangefinder camera.
History Leading to the M9
The Leica M system was introduced in 1954 with the arrival of the Leica M3. Since then changes have been incremental rather than revolutionary. Leica seems to be slow or reluctant to introduce new features, even when they have become commonplace with all of its competitors. For example, the 2002 Leica M7 was the first M to have aperture priority, a feature commonly found in almost any other serious camera since the early 1980's.
The first digital Leica M was the M8. It has a crop sensor without an infrared-blocking filter. This means images can suffer from discoloration from the invisible part of the light spectrum when shooting things such as the synthetic fabrics used in some clothes. The M9's sensor is full-frame and has no disturbing sensitivity to IR
viewfinder and rangefinder
This newest Leica has a viewfinder magnification of 0.68x. That's the same as on the M8 but just a bit below what had become the standard in analog M's; 0,72x. Framelines are mirrored in in pairs. The combinations are the same as on the M7; 35-135, 28-90 and 50-75. The rangefinder has a 69,25mm  base, the same as its siblings.
