What is Crop Factor?

Crop factor is a term used in digital photography to describe the ratio of the dimensions of a camera's image sensor to a reference format, typically 35mm film. It affects the field of view and apparent magnification of lenses used on cameras with different sensor sizes. For a detailed comparison between full-frame and crop sensors, check out my comprehensive guide on full-frame vs crop sensor cameras.
