Canon EF 11-24mm f/4L USM Lens

To experience the Canon EF 11-24mm f/4L USM Lens ultimate in wide-angle photography, the EF 11-24mm f/4L USM brings L-series construction and optics to the widest zoom lens Canon has ever made. With an expansive wide-angle range of 11-24mm, this is an ideal lens for landscapes, interior shots, and unique perspectives on subjects close and far. Its new optical design features Super UD and UD lenses that correct chromatic aberration.

Four aspheric lens elements help to minimize distortion from the center of the image to the periphery and throughout the zoom range. A Subwavelength Coating (SWC) and Air Sphere Coating (ASC) significantly reduce flare and ghosting, while a 9-blade circular aperture diaphragm creates beautiful, blurred backgrounds. For silent and fast AF, it features a rear focus system and ring USM, and can be manually focused even when in AF mode. It has a minimum focusing distance of 11 in./0.28m (extreme telephoto) for admirable performance and results even when capturing in tight spaces.

A truly versatile wide-angle zoom featuring an advanced optical design and constant f/4 maximum aperture, the Canon EF 11-24mm f/4L USM Lens is a member of the esteemed L-series of lenses designed for full-frame EOS DSLRs. One Super UD element and one UD element offer a significant reduction in chromatic aberrations while four aspherical elements help to minimize distortions throughout the zoom range and provide consistent edge-to-edge sharpness and illumination. Both SWC and ASC coatings have been applied to the elements in order to reduce lens flare and ghosting for increased contrast and color accuracy. Ideally suited for landscape and architectural photography, this lens covers ultra-wide to wide-angle perspectives and backs up its versatile zoom range with sophisticated optical components and intuitive handling.
