The Canon EF 800mm f5.6L IS USM is the longest telephoto lens from Canon. But it is actually lighter than Canon’s EF 600mm f4L IS lens. It uses a refined optical design for outstanding correction of color fringing, superb contrast and sharpness. With image stabilizer, the lens can provide up to 4 stops of correction for camera shake. The Canon EF 800mm f5.6L IS USM is ideal long-distance outdoor sports, wildlife, news photojournalism, and so on. (The sample photos are copyrighted by the owner.
