– Advanced Photo System-Classic is an image sensor roughly one-third to one-half the size of a 35mm frame of film, or full-frame image sensor. APS-C image sensors are used in most consumer-level DSLRs and in many mirrorless cameras.
Advanced Photo System type-C should not be confused with the Advanced Photographic System (APS) camera/film system, since the former is digital and the latter is analogue. APS-C is a type of image sensor found in certain digital single lens reflex (DSLR) cameras. These sensors are smaller than the ones used for the conventional 36 mm x 24 mm (35 mm) sensor SLR cameras (also called full frame DSLR cameras). Being smaller causes a 1.x multiplier for the effect of the focal distance of the lenses, in comparison with the effect of those lenses on conventional 35 mm film SLR cameras or full frame digital SLR cameras. Several manufacturers produce cameras with an APS-C sensor and some even make lenses especially for them. These lenses are found in the Canon EF-S, Nikon DX, Pentax DA and Sigma DC ranges, to name the most popular ones. The most common multiplier ratios are 1.6 (Canon), 1.5 (Nikon, Fuji, Sony, etc.), 1.3 (Canon). (1.3 crop sensors are also sometimes called APS-H.) Most manufacturers not only produce cameras with these cropped sensors, but also offer DSLR cameras with full frame sensors. .

APS-C stands for Advanced Photo System-type C, which is an image sensor format that is equivalent to approximately the size of the Advanced Photo System negative (25.1x16.7mm). The Nikon DX format image sensor is an APS-C format sensor.

A term used to describe the size of the digital imaging sensors used in almost all compact DSLRs. The name is derived from the APS (Advanced Photo System) film format that was introduced in 1996 for the amateur point-and-shoot market. The APS format is about half the size (23.6 x 15.8mm) of a standard 35mm frame (24 x 36mm) and has a 1.5x magnification factor (multiply the focal length x 1.5) for determining the 35mm equivalent focal length of lenses used on APS-C format cameras. APS-C format DSLRs from Nikon, Pentax, Fujifilm, and Sony (Alpha) contain APS-C sized imaging sensors.Canon compact DSLRs, which include EOS Rebel-series DSLRs, contain APS-C format imaging sensors that are slightly smaller than competitive compact DSLRs (22.3 x 14.9mm, so the lens factor for these cameras would be 1.6x). Although it does further reduce the effective field of view of your lenses, they are slightly more telephoto than their 1.5x brethren.For more on crop factor, see the explora article, ://www.bhphotovideo.com/explora/photography/tips-and-solutions/understanding-crop-factor Understanding Crop Factor.
