It would make very much sense for Canon to introduce a fast standard zoom with the 7DII, something like an EF-S 15-60mm f/2.8 IS USM with weathersealing. The 17-55 is nice optically, but it is not dust- or water-resistant and does not go down to a crucial 24mm equivalent. Any rumors about that? I'd buy that lens in a heartbeat for ~1000$... :
