    Overview

    The Canon EF 17-35mm f/2.8 L USM is a lightweight, professional ultrawide zoom for full-frame and 35mm cameras, offering f/2.8 speed and instant manual focus override. Optically, it features two aspherical elements and a floating system for consistent performance, but on APS-C it behaves like a standard zoom. Build quality is very good with smooth controls and fast ring-type USM AF. It suits users needing a fast wide zoom on a budget, though it's best on full-frame.
