Super telephoto zoom lens covers the range of 152–609mm (35mm format equivalent). To minimize the color aberration, a typical problem for a telephoto lens, the optical construction comprises 21 elements in 14 groups with 5 ED Lens and 1 super ED Lens. The lens achieves highest image quality in its class. The lens supports the photographer to shoot super-telephoto images hand-held with the 5.0-stop optical image stabilization, quiet high-speed autofocus driven by the linear motor, and compact and lightweight design weighing less than 1.4kg. In addition to the weather- and dust-resistant, and -10°C low-temperature operation construction, the front element is applied with water and dirt repellent coating to make the lens even tougher.
