1.2.2008 14:50Jan Povysil The Canon EF800mm f/5.6L IS USM is not only the longest focal length lens available with OIS, it is also virtually the same physical size as the EF600mm f/4L IS USM (461mm vs. 456mm), while weighing nearly 2 lbs. less (4500g/9.9 lbs. vs. 5360g/11.8 lbs.). These outstanding features were made possible by the use of a lightweight magnesium alloy lens barrel construction and a state-of-the-art super-telephoto optical system featuring 2 fluorite elements as well as Super UD and UD glass elements. The EF800mm f/5.6L IS USM is well-suited for a wide variety of long-range big money photo applications such as wildlife and nature photography as well as sports and documentary photojournalism.
