The EF17-40mm f/4L USM is an ultra wide angle Canon EF zoom lens meant for professional and high amateur SLR EOS camera users. While it is an excellent lens when used with an analog SLR camera, the EF17-40mm f/4L USM is especially well suited for digital SLR cameras with an imaging sensor size smaller than the 35mm format. Indeed on such digital SLR cameras these focal lengths can give an angle of view approximately equivalent to that of a 28-70mm lens used on a 35mm camera, which makes it the ideal standard zoom lens. The EF 70-200mm f/2.8L IS USM is an image stabilization lens with a newly developed system that can achieve stabilizer effects equivalent to approximately 3 stops in terms of shutter speed. It further has high-resolution, high-contrast optical capability, and dust and moisture resistance, making this one of the most advanced and robust models in its class.
