Canon EF 17-40mm f/4L USM Wide-Angle Zoom Lens

 The Canon EF 17-40mm f/4L USM is a professional wide-angle zoom lens designed for photographers who need reliability, sharpness, and versatility in a lightweight package. Covering a focal range that’s perfect for landscape, architecture, travel, and event photography, it offers sweeping perspectives on full-frame Canon DSLRs, and a practical wide-to-standard zoom on APS-C cameras (≈27-64mm equivalent).

Engineered with Canon’s renowned L-series optics, the lens features Super UD and aspherical elements that minimize distortion and chromatic aberrations, ensuring crisp detail across the entire frame. The constant f/4 aperture provides consistent exposure throughout the zoom range, while the ring-type Ultrasonic Motor (USM) delivers fast, silent autofocus with the flexibility of full-time manual control.

Built tough, the EF 17-40mm f/4L USM includes weather sealing against dust and moisture, making it a dependable choice for challenging outdoor conditions. Its balance of professional optical quality, durability, and portability makes it one of the most popular and affordable Canon L-series wide-angle zooms.
