From the Manufacturer
Light. Portable. Excellent handling. Sharp. And amazingly fast autofocus. The 400mm f/5.6L is all of these things, and a premier choice for wildlife and nature photographers--one of the finest telephoto lenses in the world for fast-moving subjects such as birds in flight or motor sports. It uses UD-glass elements to provide outstanding optical quality, even wide-open, and image quality is preserved when used with either the EF 1.4x II or EF 2x II tele extenders. It accepts 77mm filters, and has a built-in removable tripod collar.

See a Different Dimension
A super telephoto lens can make an ordinary scene into an extraordinary one. Its ability to see surpasses that of the human eye. It can compress images and make them look as if they come from another dimension. It opens up new realms of photographic expression. All EF super telephoto lenses are L-series lenses to provide the highest quality. The USM provides quiet and high-speed autofocusing. These lenses promise outstanding delineation and put your imagination to the test.

Customer Reviews

Great bang for the buck
It's hard to find as long a lens at a comparable price, but there is a "you get what you pay for" factor. Of all of my Canon lenses (I have seven), this is the softest and offers the least contrast. It performs best in bright light when you can stop it down to f/14 or better. I have used the 400mm lens with both the 1.4x and 2x Canon extenders (1.4 is better). It's a comparatively slow lens. BUT the 400mm f/2.8 is over $5000 more! So you can see why "bang for your buck" means something. Also, this is a _much_ lighter weight lens than the faster Canon telephotos. Finally, it is not image stabilized, so you will likely want to a solid tripod or monopod.

On balance, if you don't need the very finest optical quality, this lens is well-worth the price.

crystal clear clarity
The 5.6 aperture limits this lens for mostly outdoor photography, but then again, how often do you need a lens of this capacity for indoor purposes. I used this lens for some high school football games and to photograph buildings in the distant. The results are amazing with stunning clarity. If only it wasn't so heavy and large in size, but, I guess it could be worse.

A fantastic piece of glass
I have been using the Canon 400mm f5.6L lens for well over a year now mainly for wildlife photography, and the lens was worth every penny I paid for it. Built tough, the image quality coming out of this lens is exceptional: sharp as a tack even at f5.6 with exceptional contrast and clarity. Relatively lightweight makes for an exceptional walk around lens, and in a good deal of conditions given its focal length and weight it can be handheld. A great lens for the price.
