Canon EF800mm f/5.6 L IS USM LensThis is the longest telephoto lens among Canon's lineup and a terrific choice for long-distance application-outdoor sports wildlife news photojournalism and so on. It's actually lighter than Canon's EF 600mm f/4L IS lens weighing just under 10 lbs. It uses a refined optical design with two fluorite lens elements one UD element and one Super-UD-glass element for outstanding correction of colour fringing and superb contrast and sharpness. This super-telephoto lens uses magnesium-alloy barrel construction to enhance its light weight and has weather-resistant gaskets throughout for use in harsh conditions. It's compatible with both the EF 1.4x II and 2x II tele extenders for even more reach: EOS cameras with 45 AF points will continue to provide autofocus at the centre AF point when the lens is used with the 1.4x extender. Finally it's image stabilised providing up to 4 stops of correction for camera shake. This makes it even more practical in many situations. - L-series construction- 4-stop Image Stabilizer with tripod detection- Fluorite UD and super-UD lens elements- 4.5 kg magnesium alloy build- Super Spectra lens coatings- Ring USM auto focus with full-time manual focus
