More zoom, less aberration

The Canon EF 17-40mm f/4L USM Lens is a high-quality wide-angle zoom lens for full frame and APS-C size DSLR cameras. This lens combines one high-precision molded glass aspherical element and two replica aspherical lenses to achieve the extended zoom range, while also correcting for common aberrations that arise during zooming.

Smooth operator with fast, silent autofocus

The lens focuses as close as 11 inches (0.28m), while offering both Canon's full-time manual focus and a powerful ring-type USM for fast and silent AF. 

Achieve a natural-looking background blur

It also has a constant f/4 maximum aperture, and offers the choice of screw-in 77mm filters or a holder in the rear of the lens for up to three gel filters. It features circular aperture diaphragm for better, more natural looking background blurring.
