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. In regard to focusing performance, a ring-type Ultrasonic Motor offers fast, smooth, and near-silent autofocus, which is further benefitted by full-time manual focus operation and internal focusing design. Wide-angle zoom 11-24mm f/4 lens is compatible with full-frame Canon EF-mount DSLRs, as well as APS-C-sized models where it will provide a 17.6-38.4mm equivalent focal length range. One Super Ultra-Low Dispersion and one ultra-low dispersion element help to significantly reduce chromatic aberrations for improved clarity and color accuracy.A ring-type Ultrasonic Motor (USM), along with an internal focusing system, high-speed CPU, and optimized AF algorithms, are employed to deliver fast, precise, and near-silent autofocus performance as well as full-time manual focus override.Protective fluorine coating has been applied to the front bulbous element to resist fingerprints and smudges and to make cleaning significantly easier.
