This ultra-high quality zoom lens covers the entire zoom range from 28mm wide-angle to 300mm telephoto. With three UD lenses and three aspherical lenses, chromatic aberration and distortions are thoroughly suppressed, realizing an approximately 11x zoom range with image quality suited to an L lens. And because the lens comes with an image stabilization mechanism that can compensate for approximately 3 shutter speeds*1, users can take advantage of its full capabilities during handheld shooting at 300mm telephoto and in locations with insufficient lighting.
The lens uses environmentally friendly lead-free glass, and with an optimized lens coating and optical design, it minimizes flare and ghosts, which often occur with digital cameras. In addition, it features a zoom ring friction control mechanism, making it possible to freely set zoom operations, and enhanced dust-proof and drip-proof*2 design for shooting under severe conditions. The lens also comes with high-speed AF and full-time manual focus system. This ultrahigh-performance zoom lens meets the demands of all users from professionals to photo enthusiasts.
