Super-Wide-Angle Zoom Lens

Combining superb optics and a sleek, solid construction, the EF 17–40mm f/4 L USM is the latest in Canon’s acclaimed L series. Designed for full-frame and APS-C DSLR cameras, the lens has a super-wide angle that’s ideal for portrait, landscape, and travel photography. It features one high-precision molded glass aspherical element and two aspherical lenses, which provide an extended zoom range while correcting aberrations. A super-ultra-low dispersion glass element eliminates color bleeding along the edges of subjects and produces high image contrast and resolution. Finally, the ultrasonic autofocus motor enables smooth focusing, while the manual focus override in One-Shot AF mode allows for precise manual focusing without having to switch to MF mode.
