# APS-C > A camera sensor format smaller than full frame, which crops the image by a factor of about 1.5–1.6. Also known as: APS-C sensor, crop sensor. Category: Lighting and optics. APS-C is a sensor format of roughly 23 x 15 mm, smaller than full frame. It crops the field of view by a factor of about 1.5 to 1.6, so a 50 mm lens frames like a 75 to 80 mm lens on full frame. ## How PhotoRobot uses it PhotoRobot's camera resolution guide explains that APS-C sensors capture less of the scene with a given lens and require different settings and stronger lighting, and recommends full-frame cameras for product photography. Its Depth of Field Calculator supports Canon APS-C as well as full frame. ## See on photorobot.com - [Understanding camera resolution](https://www.photorobot.com/manuals/camera-resolution) ## Related terms - [Full-frame sensor](https://www.photorobot.com/glossary/full-frame-sensor): A camera sensor the size of 35 mm film (36 x 24 mm), preferred for product photography. - [Crop factor](https://www.photorobot.com/glossary#crop-factor): The ratio between full frame and a smaller sensor, used to compare fields of view. - [Depth of field](https://www.photorobot.com/glossary/depth-of-field): The distance range in front of and behind the focus point that appears acceptably sharp. ## Where this term appears on photorobot.com Mentioned on 6 pages.
