Is this normal?


I would say not normal - at least, I don't feel anything like that (I was shooting with my 17-55mm yesterday evening).

Yeah - the EF-S 17-55mm is equivalent to L-series lenses in optical quality, but not quite there in build quality. It's decent, better than a lot of consumer zooms, but not L. My 24-105mm feels a bit nicer to use (and I like that I can take it out in the rain), but both lenses produce equally excellent images.
