APS -C ( " Advanced Photo System Classic" ) is originally the name for one of the three recording formats of the Advanced Photo System, a process developed in 1996 by Kodak standard for photographic films.

APS with digital cameras

The term APS -C was later adopted by Canon for the format of digital SLR cameras and there inscribed image sensors, which have a size of approximately 22.5 mm × 15.0 mm.

APS -C is in digital image sensors is no standard specification, but the size can vary depending on the manufacturer and model of camera. Compared to the classical miniature film of the form factor is about 1.6 to 1.5, the aspect ratio is 3:2. The company called Nikon camera sensors in APS-C format as DX format.

Under the name APS-H cameras are marketed which have a slightly larger sensor size of about 27.9 mm × 18.6 mm, corresponding to a crop factor of about 1.3. These sensors also have an aspect ratio of 3:2, so there is due to the different aspect ratio, no reference to the same format of the APS film that defines a ratio of 16:9.

The format name of APS can be easily confused with Active pixel sensor, but the latter describes a special technique for CMOS image sensors, which is fully inserted, regardless of the sensor size.
