The KAF-10500 is a CCD

Charge-coupled device

A charge-coupled device is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. This is achieved by "shifting" the signals between stages within the device one at a time...

. In September 2006 it was announced that the sensor was to be used in the Leica M8

Leica M8

The Leica M8 is the first digital camera in the rangefinder M series introduced by Leica Camera AG on 14 September 2006. It uses a 10.3-megapixel Kodak KAF-10500 CCD image sensor.As of 15/07/2011, the most recent firmware version is 2.014.-Features:...

Rangefinder camera

A rangefinder camera is a camera fitted with a rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus...

, having been specifically designed for this application. Its size is 18x27 mm and it has 10.3 million pixels of size 6.8 μm. Compared to 35mm film

135 film

The term 135 was introduced by Kodak in 1934 as a designation for cartridge film wide, specifically for still photography. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film format...

, it has a 1.33 crop factor

Crop factor

In digital photography, a crop factor is related to the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference. In the case of digital cameras, the imaging device would be a...

. It is calibrated for an ISO sensitivity

Film speed

Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system....

 range of 160–2500.

The sensor includes indium

Indium

Indium is a chemical element with the symbol In and atomic number 49. This rare, very soft, malleable and easily fusible post-transition metal is chemically similar to gallium and thallium, and shows the intermediate properties between these two...

Tin

Tin is a chemical element with the symbol Sn and atomic number 50. It is a main group metal in group 14 of the periodic table. Tin shows chemical similarity to both neighboring group 14 elements, germanium and lead and has two possible oxidation states, +2 and the slightly more stable +4...

 oxide as a constituent material, which Kodak claims leads to low noise, high sensitivity, and wide dynamic range

Dynamic range

Dynamic range, abbreviated DR or DNR, is the ratio between the largest and smallest possible values of a changeable quantity, such as in sound and light. It is measured as a ratio, or as a base-10 or base-2 logarithmic value.-Dynamic range and human perception:The human senses of sight and...

. It is designed for use with lenses with short back focal lengths – such as those common to rangefinder cameras – by including a microlens array to reduce fall off in intensity from the center to corners of the image. Further details and aspects of the sensor were unveiled during the course of Photokina

Photokina

The photokina is the world's largest trade fair for the photographic and imaging industries. The first photokina was held in Cologne, Germany, in 1950, and it is now held biannually in September at the koelnmesse Trade Fair and Exhibition Centre...
