. Such sensors exist in many different variants depending on the manufacturer and camera model. All APS-C variants are considerably smaller than 35 mm standard film which measures 36×24 mm. Because of this, devices with APS-C sensors are known as "cropped frame," especially when used in connection with lens mounts that are also used with sensors the size of 35 mm film: only part of the image produced by the lens is captured by the APS-C size sensor. Sensor sizes range from 20.7×13.8 mm to 28.7×19.1 mm, but are typically 22.3×14.9 mm for

Comparison with other formats

The signal-to-noise ratio for a given pixel is largely defined by the number of photons per pixel and the sensor readout noise. Hence, for practical applications, the

of an APS-C sensor cannot be directly compared to either smaller or bigger sensor sizes, as its light-collecting property is largely defined by the overall optical system, rather than sensor area.

". While Canon uses a factor of 1.6×, the other four brands all use 1.5×. APS-C cameras use a smaller area to form the image than traditional 35 mm cameras, and so lenses used on APS-C format cameras have a correspondingly narrower field of view. 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.

More recently, the company introduced the EF-M line for its EOS M series of mirrorless interchangeable-lens cameras (MILCs). EF-M lenses will not physically mount on any Canon SLR, whether film or digital. The rear of an EF-M lens is considerably closer to the sensor or film plane than that of an EF (full-frame/35mm) or EF-S lens. Canon sells an optional adapter that allows EF-M bodies to accept all EF and EF-S lenses.
