I'm not sure why. I expect you could hook up the FA* 31/1.8, shoot at 1.8 and take this same image on a K-5.
The real value in FF is that we can get more resolution, diffraction limiting is farther away, and you can always crop the image to APS-C size if you need/want to.
It does have some affect on wide glass appearing wider and whatnot, but I find that to be largely irrelevant, as I can get a wider angle of view with the glass that I own.
