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 to control chromatic aberrations and color fringing while a pair of aspherical elements reduce spherical aberrations and distortion for high sharpness and clarity. Individual pieces also feature a Sub Wavelength Coating to suppress lens flare and ghosting for improved contrast and color neutrality in various lighting conditions. Besides the optical attributes, this lens is also distinguished by its fast f/1.4 maximum aperture to benefit working in low-light conditions for controlling the depth of field. The wide-angle prime 24mm f/1.4 lens is designed for use with full-frame Canon EF-mount DSLRs, however, it can also be used with APS-C models where it will provide a 38.4mm equivalent focal length. Two ultra-low dispersion (UD) elements are used to reduce chromatic aberrations and color fringing for improved clarity and color accuracy. A Sub Wavelength Coating has been applied to individual elements to control lens flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions. The floating internal focusing mechanism helps to maintain consistent image quality throughout the focusing range, from 9.8" to infinity. As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
