Describes how much an imaging sensor has been cropped in relation to its full-frame equivalent. It always describes how many times larger the full-frame is in relation to the cropped sensor. Take an APS-C sensor with a crop factor of 1.6, for instance. This indicates the sensor is 60% of the size of a frame of 35mm film. The crop factor is used to calculate how much of the equivalent of the full-frame field of view the cropped sensor will have with a lens. In order to calculate this, one multiplies the focal length of the lens by the crop factor. A 1.6 crop-factor, for instance, will give a 100mm lens the same field of view as a 160mm lens on a full-frame camera.

Indicates the distance from the film plane to the subject, usually in both feet and meters. Some digital cameras can use lenses originally designed for analogue/film cameras, and in case of digital cameras with cropped sensors the owners should take the crop factor into account when using the focusing scale.
