Chromatic aberration common in wide-angle shooting is also reduced by the inclusion of two UD lenses, which ensure optimum image quality and corner-to-corner detail. The EF 24mm f/ 1.4L II USM features Canon's near-silent Ultra Sonic Motor (USM), which provides super-fast auto-focusing with full-time manual override. The floating internal focus system also helps maintain high image quality throughout the focal range.
FEATURES: SWC (Sub Wavelength Coating) - The anti-reflective SWC (Sub Wavelength Coating) differs from conventional coatings by using a much finer structure, which minimizes ghosting and flaring across the lens surface, regardless of the angle with which light enters or exits. Ring-Type USM Motor - Canon's very best autofocusing mechanisms are in place, permitting full-time manual focusing override without requiring a switchover from AF to MF mode. L-Series - Canon's "L-Series" designation indicates that this lens meets their highest quality standards with excellent color reproduction and edge to edge sharpness
