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.
