Canon EF 300mm f/4L IS USM

Canon EF 300mm f/4L IS USM Telephoto Lens for Canon SLR Cameras

¿¿¿¿

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. It¿¿¿¿s 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 Canon¿¿¿¿s fixed focal length L-series lenses above 135mm, it¿¿¿¿s compatible with Canon¿¿¿¿s 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.

Product Description:
Compact L-series telephoto lens with an Image Stabilizer which 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 the new Stabilizer Mode 2 which steadies the image during horizontal or vertical panning. Mode 2 detects the panning direction automatically. The closest focusing distance is 4.9 feet (1.5 m).
