In reply to zebedoo:
Dunno about the lens itself, but you've gained very little at either end. 3mm at the wide end is negligible. 30mm at the other end will help for some stuff (eg portraits) but is not more than a few steps
He's gained more than 3 and 30 when you add in the crop factor. I think its 1.6 on the Canon but correct me if its not.
Sounds like a good size range to me.
Cant comment on the lense itself, Im a Nikon fan....
