Covering a flexible wide-angle focal length, the Canon EF 17-40mm f/4L USM is a robust zoom lens from the esteemed L-series collection, offering a consistent f/4 maximum aperture alongside an advanced lens architecture and sturdy build. It includes one Super Ultra-Low Dispersion element and three aspherical elements to greatly minimize chromatic and spherical distortions for increased sharpness, lucidity, and color precision. Additionally, a Super Spectra coating has been used to reduce the impact of flare and ghosting for better contrast in challenging lighting scenarios. Alongside its imaging attributes, this lens integrates a ring-type USM and an internal focusing system to deliver fast, silent, and precise autofocus, with the added benefit of manual focus override. Plus, the construction includes weather-sealing for operation under adverse weather conditions.
