Rent NowThe Canon EF 17-40mm f/4L USM Lens is a professional wide-angle zoom designed for Canon EF-mount DSLR cameras. As part of Canon’s L-series lineup, this lens combines a versatile focal length range, a constant f/4 maximum aperture, and durable construction. It is well suited for landscape, architecture, travel, and general photography.
Covering a 17-40mm focal length range, the lens provides an expansive field of view on full-frame cameras, making it ideal for capturing landscapes, interiors, and architectural subjects. When used on Canon APS-C cameras, it offers a 27.2-64mm equivalent focal length range. The constant f/4 aperture maintains consistent exposure throughout the zoom range.
The optical design incorporates one Super Ultra-Low Dispersion (UD) element and three aspherical elements to minimize chromatic aberrations, distortion, and color fringing. Canon’s Super Spectra coating further reduces flare and ghosting, helping maintain image contrast and accurate color reproduction in challenging lighting conditions.
Equipped with a ring-type Ultrasonic Motor (USM), the lens provides fast, quiet, and accurate autofocus performance. Its internal focusing mechanism allows the front element to remain stationary during focusing, while full-time manual focus override provides additional control when precise adjustments are needed.
Built for professional use, the lens features durable L-series construction with dust- and moisture-resistant sealing. A 77mm front filter thread accommodates compatible filters, while a rear filter holder provides additional flexibility for specialized photographic applications.
The Canon EF 17-40mm f/4L USM combines wide-angle versatility, professional-grade optics, and reliable autofocus in a durable zoom lens. Its compact design and consistent f/4 aperture make it a practical choice for photographers working with landscapes, architecture, and everyday subjects.
