The EF 800mm f/5.6L IS USM Lens from Canon is currently Canon’s longest telephoto lens, and an excellent choice for any long-distance application such as outdoor sports, wildlife, and photojournalism. Even though it has a long 800mm focal length, the magnesium alloy used in the construction for this lens makes it lighter then the 600mm f/4L lens, weighing in at less than 10 lb.

This lens shares the same lightweight, weather-resistant construction as the rest of the L-series super telephoto lenses, as well as their improved control layout, weight distribution, and mechanical manual focus. Its two-mode Image Stabilizer system allows the use of shutter speeds up to four times slower with no perceptible increase in image blur. Mode 1 is best used for still subjects while Mode 2 is optimized to pan with moving subjects.
