with that said

Canon EF-S lens mount - Wikipedia, the free encyclopedia

if you look at that wiki article it points out that no L series lenses which I'm sure that's what Josh's 2.8 is are EF-S mount in fact the selection of true EF-S lenses appears relatively small.
It is very possible his lens is an L Series and not an EF-S. It's a canon. Ewwww.
