The Canon 24mm f/1.4 is an L-series, high-performance, wide angle lens. One of Canon's newest designs, this lens delivers excellent sharpness across all settings. Lens elements have a newly-designed anti-reflective SWC (Sub Wavelength Coating) which uses extremely fine structure to minimize ghosting and flaring. The large f/1.4 maximum aperture provides excellent low-light performance and depth of field control. This lens gives a 84° angle of view on a full-frame camera body.
