When bought for a cropped-frame body Good points Canon 'L' build and optical quality Fast and quiet USM focusing motor Constant f4 aperture throughout range Will also work on full-frame body Bad points Shorter zoom range than kit lens No IS (although not particularly necessary) Overkill if not considering full-frame in future Canon EF-S 17-85mm more flexible for most	Scores (relative to 18-55mm kit lens)
