=== Updated usage ===
Presently the format names APS-C and APS-H are most often used in reference to various makes of digital SLR that contain imaging sensors that have approximately the same [[crop factor]] as those formats, albeit with different actual dimensions, as APS-H digital sensors have a 3:2 aspect ratio, not the 16:9 aspect ratio of the APS-H film frame. Some of the lenses originally released with the APS SLRs have survived and are now marketed towards use on "APS" digital SLRs for the same reason. In reference to digital cameras, ''APS'' may also mean [[active pixel sensor]], a type of [[CMOS]] [[image sensor]].
