I have a 24-105, and my girlfriend has a 28-135. The 24-105 creeps much less than the 28-135, almost exclusively when the camera is being carried and not while in use. I've rented the 24-70, and I think it crept even less, though by no means was creep absent.


For what it's worth, she used my 24-105 on her 40D a lot over the past four weeks (three big gigs), and REALLY liked it. Admittedly, that was also with a 10-22 EF-S and a 70-200/4IS on a Rebel and a rented 50D, so she didn't have to change lenses. Meanwhile, I was using the rented 24-70 on a 5D and later a 1D Mark III, and found that I really liked the 24-70. I didn't miss IS much, and I didn't miss the 70-105 range, but the aperture came in handy.


I suspect I'll be buying a 24-70 soon, and letting her use the 24-105 most of the time.
