From the Manufacturer
Bring your subjects closer while shooting sports or wildlife with the Canon EF 300mm f/4L telephoto lens. The lens is equipped with Image Stabilizer (IS) technology, which compensates for camera shake by providing the equivalent effect of a shutter speed two stops faster. The camera provides two IS modes: Stabilizer 1, the same mode featured on the EF 75-300mm lens, and Stabilizer 2, which steadies the image during horizontal or vertical panning. The lens is also half the weight of the 300mm f/2.8L IS, with a close focus distance of 4.9 feet. And like all of Canon?s fixed focal length L-series lenses above 135mm, it?s compatible with Canon's EF 1.4x II and 2x II Extenders.

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. Itís less than half the weight of the 300mm f/2.8L IS, and it focuses to an incredibly close 4.9 ft/1.5m, filling the frame with a subject the size of a postcard. Like all of Canonís fixed focal length L-series lenses above 135mm, itís compatible with Canonís EF Extenders 1.4x II and 2x II.
Long and Fast
A telephoto lens is essential to any serious photographer. 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.
