Canon EF 17-40mm f/4L USM 17-40mm
The constant f/4 aperture and weather-sealed L-series construction provide consistent exposure and durability across the 17-40mm full-frame range. Its ring-type USM autofocus is fast and silent, while a non-rotating 77mm filter thread simplifies polarizer use. This lens is best for travel photographers who need a rugged, versatile ultra-wide zoom without the bulk of an f/2.8 lens.
