I own it and the 24-105 and don't use either on my 7D. I finally broke down and bought a 17-55 when Adorama dropped the price down to $950 a while back. For me, 24mm isn't wide enough on 1.6x bodies and barely wide enough for certain things on 1.3x bodies. My advice if you are shooting a 1.6x body is the 17-55 or the 15-85 if you need more range.
