Canon EF 14mm f/2.8L II USM Lens

Ultra-wide angle lenses have always been in demand by architectural, corporate, and other top pro photographers. This new lens features completelyredesigned optics including 2 high-precision Aspherical elements and two totally new UD-glass elements. The result is superior image quality: bettercontrast and sharpness at the outer edges, and a reduction in chromatic aberrations that can sometimes be seen with high-resolution digital SLRs. Itsdiagonal angle of view is an impressive 114-anything larger would be a Fisheye lens. It has a built-in lens hood, and has been dust- and moisture-proofed. The lens uses a rear focusing system, high-speed CPU, and a powerful ring-type USM with revised electronics for faster, more responsive AF.This lens continues the proud tradition of superior clarity optics found in L-series Canon lenses.

A ring-type ultrasonic motor (USM) uses ultrasonic frequency vibrations to drive responsive, near-silent high speed auto focus. Good holding torquestops the focusing lens group with precision without overshoot. Full time manual focus override is available without having to switch out of AF.

Two UD (ultra-low dispersion) glass lens elements correct chromatic aberration to achieve high resolution and contrast, without color fringing onsubject outlines.

Two AL aspherical lens elements suppress aberrations for high image quality at all focal lengths.

Equipped with a fixed, petal-type hood and a gelatin filter holder at the rear.

Only lead free glass is used in the lens construction.
