Canon U.S.A. today announced two new wide angle lenses and a updated version of its popular 24-70mm zoom lens. The new EF 24-70mm f/2.8L II, EF 24mm f/2.8 and EF 28mm f/2.8 lenses use a rear focusing system, high-speed CPU, and a ring-type Ultra Sonic Motor (USM) with optimized AF algorithms for faster auto focusing. The 28mm and 24mm primes offer IS however the 24-70mm does not.
