The Canon EF 14mm f/2.8L II USM Autofocus Lens is a bright
lens that provides an ultra wide-angle view, and has 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.
The 14mm f/2.8L II USM lens uses a rear focusing system,
high-speed CPU, and a powerful ring-type USM with revised electronics
for faster, more responsive AF. This wide aperture lens is the ideal
choice for architectural, corporate, or other pro-level photography.
