Canon EF 14mm f/2.8L II USM review
Ultra-wide angle lenses have always been in demand by architectural,
corporate, and other top pro photographers. This new lens features
completely redesigned optics including 2 high-precision Aspherical elements
and two totally new UD-glass elements. The result is superior image
quality: 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 diagonal 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.
