725g for a crop f/2 zoom is heavy but not terribly so, but the Sigma 18-35mm f/1.8 is very close to that weight, offers a larger zoom range and is fractionally faster. That said, going down to 14mm for crop is a nice add -- the Sigma's 18mm wide end would handcuff a number of folks for a standard zoom.
