Canon 24mm F/1.4L II USM
Combining a favored wide-angle focal length with a bright maximum aperture, the EF 24mm f/1.4L II USM is a Canon L-series lens characterized by a robust physical construction and sophisticated optical design. Two ultra-low dispersion elements help control chromatic aberrations and color fringing, while a pair of aspherical elements reduce spherical aberrations and distortions for high sharpness and clarity. Individual elements also feature a Sub Wavelength Coating to suppress lens flare and ghosting for improved contrast and color neutrality in a variety of lighting conditions. In addition to the optical attributes, this lens is also distinguished by its fast f/1.4 maximum aperture to benefit working in low-light conditions to control depth of field. Additionally, this lens sports a ring-type USM for fast, quiet autofocus performance and full-time manual focus override, and an internal floating focus mechanism also helps maintain consistent image quality throughout the focus range.
