Canon EF 11-24mm f/4L USM Ultra-Wide Zoom Lens with Ring USM Autofocus for EOS DSLR Cameras (Black) - New

Widest Rectilinear Zoom Canon Has Ever Built

The EF 11-24mm f/4L USM brings L-series construction to the most expansive wide-angle range available, starting at an unprecedented 11mm focal length. This professional zoom lens captures breathtaking landscapes, dramatic architectural interiors, and unique perspectives impossible with conventional glass. With a constant f/4 maximum aperture throughout the 11-24mm range and advanced optical elements including one Super UD and one UD lens element, chromatic aberration is minimized across the entire frame. Four aspherical lens elements work together to reduce distortion from center to edge, maintaining excellent sharpness even at the extreme 11mm wide end.

Advanced Coating Technologies Suppress Flare

Canon's Subwavelength Coating (SWC) and Air Sphere Coating (ASC) combine to dramatically reduce flare and ghosting, even when shooting into direct light sources—critical when working with such an expansive field of view. The 9-blade circular aperture diaphragm creates smooth, natural bokeh in out-of-focus areas. A minimum focusing distance of just 0.28m (11 inches) at the telephoto end allows remarkably close working distances, opening creative possibilities for dramatic perspective and environmental portraits.

Professional Build and Lightning-Fast Autofocus

Ring-type Ultrasonic Motor (USM) technology delivers near-silent, high-speed autofocus performance, while the rear focus system maintains consistent lens length during focusing. Full-time manual focus override lets you fine-tune focus instantly without switching modes. The robust L-series construction features weather-resistant seals throughout the barrel, protecting against dust and moisture in challenging shooting conditions. A high-speed CPU and optimized AF algorithms ensure precise focus tracking even in complex scenes.
