Compact L-series telephoto lens with an Image Stabilizer that compensates for camera shake with the equivalent effect of a shutter speed two stops faster

A more portable 300mm telephoto lens. Two UD-glass elements effectively correct secondary spectrum. Superb resolution and contrast. Astigmatism is also corrected, and background blur is soft and nice. Built-in hood with a locking mechanism.
