Most of the hits for the 24-105 dust issues are present when it is noted that the 24-105 is dust and moisture resistant.However, the 17-55mm is known to have mechanical issues that don't end with dust and for something that costs $1000 that is inexcusable IMO (just like the Sigma lenses that don't AF). It has a higher failiure rate at lensrentals.com than other lenses -- I know you said that's not the way to judge a lens, but heck, the other lenses aren't failing!


I know the 17-55mm is a very good lens, but I wouldn't buy myself one. I try to convince myself to but can't.
