Overview An impressive ultra wide-angle prime, the EF 14mm f/2.8L II USM is a Canon L-series lens well-suited for landscape, nature, and interior photography applications. Its relatively bright f/2.8 maximum aperture is well-suited to working in difficult lighting conditions and also makes this lens an ideal choice for astrophotography. The optical design incorporates two aspherical elements and two ultra-low dispersion elements to control both spherical and chromatic aberrations in order to realize a high degree of sharpness, clarity, and color accuracy. A Super Spectra coating has also been applied to suppress flare and ghosting for increased contrast and color fidelity when working in backlit and harsh lighting conditions. A ring-type USM and internal focusing mechanism also afford quick, quiet, and accurate autofocus performance, as well as full-time manual focus override. Additionally, this lens is weather-sealed for use in trying climates. Ultra wide-angle 14mm prime is compatible with full-frame Canon EF-mount DSLRs, as well as APS-C-sized models where it will provide a 22.4mm equivalent focal length range. Bright f/2.8 maximum aperture benefits working in low-light conditions and suits astrophotography applications. Two ultra-low dispersion elements are used to minimize chromatic aberrations as well as eliminate color blurring around the edges of subjects. Two aspherical elements help to minimize distortions and spherical aberrations in order to maintain edge-to-edge sharpness and illumination. Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions. A ring-type Ultrasonic Motor (USM), along with an internal focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override. As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions. Built-in lens hood helps to block stray light and also protects the bulbous front element. Lens's design accepts rear insert-type gelatin filters, which are cut-to-size and inserted behind the rear lens element.
