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 digital sensor. The most commonly used definition of crop factor is the ratio of a 35mm frame's diagonal (43.3mm) to the diagonal of the image sensor in question; that is, CF=diag35mm/diagsensor. Given the same 3:2 aspect ratio as 35mm's 36mm x 24mm area, this is equivalent to the ratio of heights or ratio of widths; the ratio of sensor areas is the square of the crop factor.
The crop factor is also commonly referred to as the focal length multiplier ("FLM") since multiplying a lens focal length by the crop factor or FLM gives the focal length of a lens that would yield the same field of view if used on the reference format. For example, a lens with a 50mm focal length on an imaging area with a crop factor of 1.6 with respect to the reference format (usually 35mm) will yield the same field of view that a lens with an 80mm focal length will yield on the reference format. It is important to note that the focal length of the lens does not change by using a smaller imaging area; the field of view is correspondingly smaller because a smaller area of the image circle cast by the lens is used by the smaller imaging area.
