Canon EF 300mm f/4L IS USM Super Telephoto Lens

The compact Canon EF 300mm f/4L IS USM telephoto lens equipped with Canon's optical image stabilization system. The Canon EF 300mm USM is essential to any serious photographer.

Bring your photographic subjects closer with this Canon EF 300mm f/4L IS USM Telephoto Lens. This compact Canon EF 300mm USM L-series telephoto lens with an Image Stabilizer compensates for camera shake with the equivalent effect of a shutter speed two stops faster.

Two Image Stabilizer modes are provided: Stabilizer Mode 1 (the same mode featured on the EF 75-300mm f/4-5.6 IS USM) and Stabilizer Mode 2, which steadies the image during horizontal or vertical panning. Mode 2 detects the panning direction automatically. The closest focusing distance is 1.5 m.

The Canon EF 300mm f/4L IS USM Lens features excellent optics and superb handling in a compact package with Image Stabilization. The IS allows safe hand holding at shutter speeds up to two stops slower than otherwise possible--making it even more useful in low-light levels.

For sports action, you will need a fast shutter speed and a long focal length. A large maximum aperture allows a faster shutter speed. In this telephoto lens line-up, the focal lengths range from 135mm to 300mm. If you want compactness, choose a lens with a smaller maximum aperture.

Note: With the following cameras, the Image Stabilizer does not operate when Extender EF 2x is attached to the lens: EOS 650, 620, 630/600, RT, 700, 750, 850, EOS-1, A2/A2E, 10s, Elan, Rebel/Rebel S, Rebel II/Rebel SII.
