I think small is very relative, even for me (i think as an average size asian, i qualify as small ) the EOS rebel Xs feels to small and needed a battery holder just to make it right.
Add to that none of the zoom lenses are considered small, there's light zoom, but I don't think there's a small AF zoom.
So i guess if small is the question any of the entry level ( EOS rebel, up to n65, pentax *st, etc) paired with any of the 50mm 1.8 or 1.7 would be the one I choose ( that being said the likes of mid class body like elan7 and F80 is not larger and with better functions)
