Description
This unique lens is very light, weighing just on 10kg. 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 the ultimate in weather sealing 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.
