IMHO the question of telephoto vs wide as it relates to APS-C vs FF is a moot one.
I shoot ultra-wide more often probably anybody on this list and the Sigma 10-20mm gives me a 15-30mm equiv. FOV on APS-C. In the "old days" a 15mm rectilinear was as wide as you could buy. On the other end, when I shoot shoot telephoto, I'm glad to have the Bigma be a 75-750mm equiv FOV with the 1.5x focal length multiplier. The APS-C gives me a 15-750mm focal length range with my full frame capable lenses. I'd be giving up about 250mm on the long end and next to nothing on the short end if I switched to a full frame Pentax.
