It will probably give the images more pixel resolution. Consider, for example, a CSC with the micro-four-thirds (MFT) sensor format, which has a 2x crop factor.
The crop factor affects the field of view. A bird that fills the frame of the MFT, will occupy only half of the frame, when the same focal length lens is used on FF camera at the same distance from the bird.
However, those are linear dimensions, so the effect will be to reduce the pixel resolution by a factor of 2-squared, i.e. the area of the FF sensor used to make the same photo of the bird will be divided by 4, so that the crop image from a 24 megapixel FF sensor image would have only 6 megapixels.
By cropping, it would require a 64 megapixel FF camera to give the same pixel resolution image as would be captured by a typical 16 megapixel MFT camera, when using the same focal length lens at the same distance from the subject.
(Please note that this Post is about pixel resolution figures only, and makes no comment on any of the many factors affecting images from MFT and FF cameras.)
Cheers.
