The world's first 600mm lens with an Image Stabilizer, for added steadiness and sharpness when working with a monopod 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, less "front-heavy" design, and mechanical manual focus.
