For examples:
comparing a 18mm lens on a FF cam, with a 12mm lens on 1.5x crop cam, will there be differences in the perspective distortion? (keystone?)
I've read that telephoto make the background seem closer to the subject (compression), so would this effect be more pronounced if i move a 50mm from a FF onto a 1.5x crop? (getting 75mm)
