=== Sensor size and angle of view ===
{{Unreferenced section|date=December 2019}}
Cameras with digital image sensors that are smaller than the typical 35&nbsp;mm film size have a smaller field or [[angle of view]] when used with a lens of the same [[focal length]]. This is because the angle of view is a function of both focal length and the sensor or film size used.

The [[crop factor]] is relative to the [[135 film|35mm film format]]. If a smaller sensor is used, as in most digicams, the field of view is cropped by the sensor to smaller than the 35&nbsp;mm full-frame format's field of view. This narrowing of the field of view may be described as crop factor, a factor by which a longer focal length lens would be needed to get the same field of view on a 35&nbsp;mm film camera. [[Full-frame digital SLR]]s utilize a sensor of the same size as a frame of 35&nbsp;mm film.

Common values for field of view crop in DSLRs using active pixel sensors include 1.3x for some [[Canon Inc.|Canon]] (APS-H) sensors, 1.5x for [[Sony]] APS-C sensors used by Nikon, [[Pentax]] and [[Konica Minolta]] and for Fujifilm sensors, 1.6 (APS-C) for most Canon sensors, ~1.7x for [[Sigma Corporation|Sigma]]'s [[Foveon]] sensors and 2x for [[Kodak]] and Panasonic 4/3-inch sensors currently used by [[Olympus company|Olympus]] and Panasonic. Crop factors for non-SLR consumer compact and [[bridge digital camera|bridge]] cameras are larger, frequently 4x or more.
