The assumption has to be to keep framing the same and if that is the case then either you are backing up or using a shorter focal length with a smaller sensor. The end result is closer to the myth than to the debunking of that myth.
Again, Rondec, that's changing the subject distance.
So let's cut out the middle man in this 'explanation'.
A full frame camera has a different field of view, nothing else.
A K-5 is a K-1 sensor cut in half, let's not ascribe to it magical properties as full frame fetishists have done for years.
A panorama from an APS-C camera, same distance, aperture, and lens, gives the same picture.
