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 lens, tripod is a must for some.
The only non-image stabilized offering of the three 400mm lenses Canon has, produces excellent images. This is a good lens for wildlife photography, especially on a cropped sensor Canon, which makes this lens a 640mm equivalent. The built-in hood is a nice alternative to the plastic ones you have to put on yourself (and remember to carry with you!), but it does add to the weight a bit, if that's a consideration. Canon includes a tripod ring, another good move on Canon's part, saves you an accessory to buy separately. But the lack of IS is a bit of a limitation for me, as the size and weight of the lens makes handholding it a problem - hand shake blur is evident except for shots taken in the very brightest of conditions. If handholding the larger lenses causes you problems in general, you might want to consider springing for an image-stabilized alternative. Otherwise this lens is a strong performer and I've been happy with it.

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.
