That seems incorrect. If the camera is in the same position, the FF image will show more of the scene than the crop image. You cannot "enlarge" a FF image to match a crop sensor image - you need to CROP it.

I know you know.....

35mm has always been refered to as full frame, it`s not a digital thing. Many years ago there was a little used format called half frame, where you got 72 exposures from a standard roll of 35mm film. Didn`t catch on though.
