COMMENTS: Canon's premium mid-range zoom for EOS APS-C DSLRs (DRebel XT, EOS 20D, EOS 30D). It's the approximate equivalent of a 27-88/2.8 on a full frame camera. The EF-S 17-55/2.8IS USM has Canon's latest generation of Image stabilization which should give an extra 3 stops of "handholdability". Canon don't give any EF-S lenses the "L" designation, but if they did, this lens would probably be a candidate.
