EF 800mm f/5.6L IS USM
The ultimate Canon EF lens for telephoto power, for photographers and HD video users who need to bridge long distances. This brilliant lens is the lightest in its class, at roughly 10 pounds (4500g) – lighter than the previous-generation 400mm f/2.8 IS lens. For super-tight outdoor sports images, impressive wildlife or bird pictures, and long-range daylight surveillance, the 800mm is unmatched. It's super-sharp, and has Image Stabilization (up to 4 stops of correction for camera shake) to make it even more practical when monopod-mounted.
- A thoroughly professional lens, with strong build quality and superb optics
- Fast and silent AF, with Canon's powerful ring-type Ultrasonic motor, for still images; excellent AF focus tracking performance with moving subjects in AI Servo AF
- Superb optical performance, even when shooting at widest f/5.6 aperture; sufficient "speed" for use even in overcast or shade conditions outdoors – especially with recent EOS bodies that offer excellent image quality at higher ISOs
- Compatible with all Canon EF 1.4x and 2x tele extenders – with EF 1.4x, AF at center point (only) with EOS bodies with 45-point AF system; No AF with current EOS bodies when used with EF 2x
