To experience the 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.
Featuring a rear focus system and ring USM, the EF 11-24mm f/4L USM is perfect for silent and fast AF, while the fluorine coatings on the front and rear elements help to reduce smears and fingerprints. With a minimum focusing distance of 11 in./0.28m (extreme telephoto), this lens is ideal for shooting in tight spaces, while the compact design and integrated hood make it easy to take with you wherever you go.
