## Definition

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.

For teachers: 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.

## Examples

- 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.

## Usage notes

- Usually functions as a modifier before another noun, such as 'sensor' or 'camera'.
