What does "crop factor" mean?
yup, as above. Often seen posts talking about 1.4x, etc crop factor, but never understood what it means.

Crop factor is unique to digital coz the size of the image sensor is smaller then a 35mm film size. So u need to X1.5 or whatever it is to get the same as a 35mm file size. So the factor applies to the lens also, so if u using a 50mm lens X the factor(1.5) u get 75mm instead.

it only affects DSLR cameras as there is a legacy frame size to refer to.
Eg. as above: if you mount a 50mm lens you will get a FOV of 75mm (with 1.5 Crop factor), the lens is still a 50mm, just that the resulting image has been cropped.
