This is a high-performance super-telescopic zoom lens that features, for the first time, the Supersonic Wave Drive (SWD) autofocus system which enables the lens to achieve an AF speed about two times faster than the previous ED 50-200mm f2.8-3.5 model. ED lens elements are used extensively to correct the color blurring that can occur when telescopic lenses are extended to their maximum focal length, while the digital-dedicated design ensures high-quality performance with clear, crisp images from edge to edge. Close-up shooting capability is also superb, with a minimum shooting distance of just 1.2 meters throughout the zoom range.
