The crop factor is sometimes referred to as "magnification factor", [5] "focal length factor" or "focal length multiplier". [6] This usage reflects the observation that lenses of a given focal length seem to produce greater magnification on crop-factor cameras than they do on full-frame cameras. This is an advantage in, for example, bird ...
Current Q-series cameras have a crop factor of 4.55. When full-frame sensors were first introduced, production costs could exceed twenty times the cost of an APS-C sensor. Only twenty full-frame sensors can be produced on an 8 inches (20 cm) silicon wafer, which would fit 100 or more APS-C sensors, and there is a significant reduction in yield ...
Equivalent depth of field can be calculated the same way using the crop factor. [3] For example, a 50mm f/2 lens on a 2× crop factor Micro Four Thirds camera would be equivalent to a 100 mm (= 2×50 mm) f/4 (= f/(2×2)) lens on a full-frame digital SLR in terms of field of view, depth of field, total light gathered, [4] and diffraction effects ...
For example, a 24 mm lens on a camera with a crop factor of 1.5 has a 62° diagonal angle of view, the same as that of a 36 mm lens on a 35 mm film camera. On a full-frame digital camera, the 24 mm lens has the same 84° angle of view as it would on a 35 mm film camera.
Digital sensors are usually smaller than 35 mm film, and this causes the lens to have a narrower angle of view than with 35 mm film, by a constant factor for each sensor (called the crop factor). In everyday digital cameras, the crop factor can range from around 1, called full frame (professional digital SLRs where the sensor size is similar to ...
For example, a 28 mm lens is a wide angle lens on a traditional 35 mm camera. But the same lens on an APS-C camera, with a lens factor of 1.6× (relative to a standard full-frame 35 mm format camera), has the same angle of view as a 45 mm (28 mm × 1.6 lens factor) lens on a 35 mm camera—i.e. a normal lens.

Canon has launched its first EOS R APS-C crop sensor cameras, the 32-megapixel EOS R7 and 24-megapixel EOS R10.
Cameras that have a smaller sensor than full-frame (such as APS-C and Micro Four Thirds) differ in having a crop factor. Digital cameras with a larger sensor than full-frame are called medium format, named after medium format film cameras that use the 120 and 220 film formats (although their sensors are generally much smaller than the frame ...
