Your long-distance specialist

If you're like most serious photographers, you probably won't be using this lens every day. But — if you shoot wildlife, or sports, or you need some extra reach for breaking news? Having this lens in your camera bag could make the difference between getting that one-chance-only shot or coming home empty-handed. With a constant maximum aperture of f/4, it's got exceptional light-gathering capacity for its class. This lens' super telephoto range gives you compositional flexibility while remaining at a distance. And the built-in, ultra-quiet SWM (Silent Wave Motor) will take care of the big job of acquiring sharp focus over a long distance, while allowing the flexibility for seamless manual override.

Exceptional optical quality

While this super telephoto zoom lens is optimized for full-frame cameras, DX-format cameras can benefit as well. The apparent focal length will increase by a factor of 1.5X, so this 200-400mm lens will have a 300-600mm equivalent length on your APS-C sensor cameras.

Four extra-low-dispersion optical elements and proprietary Nano-Crystal coatings yield a lens that is sharp, clear, and free of artifacts like color fringing, ghosting, flaring, and distortion.
