What is the Nikon D3100 Crop Factor?


The Nikon D3100 has a 1.5x crop factor.

Crop factor is helpful for determining the angle of view an image will be captured with. APS-C sensors cover a smaller area than full frame sensors. That smaller area is the same as if it was “cropped” from a larger image.

To get the same images from a APS-C sensor paired with a 50mm lens, a 75mm lens would have to be used on a camera with a full frame sensor.
