Different digital camera sensor sizes, as compared to 35mm film format.
Green = Canon 1.3x (rare),
Red = Nikon DX 1.5x (common),
Blue = Canon 1.6x (common).
Nikon FX and Canon full-frame are the same size as 35-mm film.

This diagram may help you understand about "crop factor". Any given lens will project the same field-of-view on every camera. The difference is the size of each camera's sensor.

"Full frame" (FX) digital cameras have sensors the same size as 35-mm film ratio used in film cameras: 24-mm x 36-mm.

"Cropped" (DX) digital cameras have smaller sensors (approx 16-mm x 24-mm) which see & record a smaller area of the image projected by the lens. This is generically called an APS-C size sensor.

On Sony, Fuji, Nikon DX, and other APS-C cameras, we use a crop factor of 1.5x to figure the apparent view, which would match the lens needed on a 35-mm film camera to capture the same field-of-view.

On Canon APS-C cameras (slightly smaller sensors), we use a crop factor of 1.6x to figure the apparent view, which would match the lens needed on a 35-mm film camera to capture the same field-of-view.

Olympus and other 4/3 size sensors, not depicted here, are exaclty half the size of a full frame sensor, resulting in a crop factor of 2x.
