Canon EF L 17/35 mm F 2.8 USM Features: A large aperture, super wide angle zoom lens with the widest view of any lens in its class. The optical system has two aspherical elements, including the first lens element which is a ground and polished aspherical glass lens element, thoroughly eliminating the distortion that is normally a problem with wide angle zoom lens. This lens delivers sharp and crisp performance throughout the entire zoom range. Its ring USM (Ultrasonic Motor) drive and inner focusing with floating construction contribute to silent and fast AF, full-time manual focusing and superb picture quality in close-range photography. Since the front lens element does not rotate during focusing, use of circular polarizing filter is facilitated. The drop-in gelatin filter holder at the rear can hold three filters. A large, dedicated, petal-shaped lens hood offers superior light shading.

Canon EF L 28/70 mm F 2.8 USM High-performance standard zoom lens whose maximum f/2.8 aperture can be used at all focal lengths. It includes the normal 50mm focal length and a minimum focusing distance of 50cm. The large aspherical element helps obtain a high image quality comparable to single focal length lenses.

Canon EF L 70/200 mm F 2.8 USM Features: This large aperture, super high image quality telephoto zoom lens provides performance comparable to that of a single focal length lens, with a wide zoom range. This lens is developed as a successor to the EF 80-200mm f/2.8L. Its major features include: a ring USM (Ultrasonic Motor) drive, built-in full-time manual focusing, short minimum focusing distance of 1.5m, high marginal illumination, and compatibility with Extenders EF1.4X and EF2X (extends the zoom range with AF to 98-280mm f/4 or 140-400mm f/5.6 respectively). Although this is a large aperture telephoto zoom lens, it is equipped with four low refraction/low dispersion UD (Ultra-low Dispersion) glass lens elements (2nd,3rd,11th & 13th) that offer excellent contrast and sharpness. This is a lens that deserves to be known as a super high performance telephoto zoom lens .
