This is the longest telephoto lens among Canon's lineup, and a terrific choice for any 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 color 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 center AF point when the lens is used with the 1.4x extender. Finally, it's image stabilized, providing up to 4 stops of correction for camera shake. This makes it even more practical in many situations.
Best Gift ever!
I got this lens as a gift from my mother. It is the best gift ever. It is very heavy and you need a tripod to use with it. I tried using a mono-pod, but had better results/luck on a tripod. I am not sure Arnold Schwarzenegger could hand-hold this one for long, even in his youth!
There is a learning curve and some adjusting to get used to it, but it is a great lens for wildlife. I was lucky and got this as a gift, but if you have the $$$, it is a great lens.

Best telephoto lens I own
Resolution has always been my highest priority and this lens certainly is the best.
The auto-focus features are superb.
After using the 600mm f/4 L lens for years trading it in for the 800 was the best trade I've ever made. It is lighter, a longer focal length and the stabilizing features are excellent.
Would recommend a gimbal tripod head, with one the system
can be manipulated with ease.
