The world's first 600mm lens with an Image Stabilizer for added steadiness and sharpness when working at slower shutter speeds. It shares the same lightweight, weather-resistant construction as the 300, 400 and 500mm IS Super Telephoto lenses, as well as their improved control layout, improved weight distribution, and mechanical manual focus.
