APS
n. uncountablen. Stands for Advanced Photo System. A type of camera sensor that is smaller than a standard piece of film. It is common in many digital cameras used by hobbyists and professionals.
n. Abbreviation for Advanced Photo System. An image sensor format approximately equivalent in size to the Advanced Photo System 'classic' negative. Often used to distinguish smaller-sensor cameras from 'full-frame' models.
My new camera has an APS-C sensor.
Photographers often choose APS-C cameras because the smaller sensor allows for more compact and lightweight lens designs.
While full-frame sensors offer superior low-light performance, the APS-C format remains a popular choice for wildlife photography due to the effective focal length increase provided by the crop factor.
Usually functions as a modifier before another noun, such as 'sensor' or 'camera'.
