The Canon 24mm f/1.4L II features two high-precision, large-diameter aspherical lenses for sharpness across the sensor, even in peripheral areas of full-frame sensors. Lens elements have an anti-reflective SWC (subwavelength coating) that minimizes ghosting and flaring across the lens surface, regardless of the angle through which light enters or exits.

It also features two UD (ultra low dispersion) lens elements to minimize chromatic aberrations and incorporates rear-focusing, ultrasonic, quiet and high-speed autofocus with full-time manual override. A circular aperture provides beautiful, out-of-focus detail and offers legendary dust-resistant and water-resistant L-series construction.
