The EF 14mm f/2.8L II USM Lens from Canon offers a bright maximum aperture and provides an ultra wide-angle view with the shortest focal length in the line-up of L-series lenses. Its diagonal angle of view is an impressive 114° - anything larger would be a fisheye lens.
This lens features completely redesigned optics, including two high-precision Aspherical elements and two UD-glass elements. This results in better contrast and sharpness at the outer edges, and a reduction in chromatic aberrations that can sometimes be seen with high-resolution digital SLRs. Its minimum focus distance is 7.9" and its truly circular diaphragm helps to create a pleasing out-of-focus background.
The 14mm f/2.8L II USM lens uses a rear focusing system, high-speed CPU, and a ring-type ultrasonic autofocus motor (USM) with revised electronics for faster, more responsive and quiet AF. Manual focus override allows for precise manual focus even in AF mode.
