The 11-20mm F2.8 is a fast-aperture zoom lens covering a focal length range from ultra wide-angle 11mm to 20mm, with a maximum aperture of F2.8 across its full range of focal lengths. With a surprisingly compact and lightweight design for a fast ultra wide-angle zoom, the lens feels well balanced when attached to a compact APS-C mirrorless camera body, making it ideal for daily use.

Despite its small, lightweight design, the lens delivers high-level imaging power with its uncompromising optical design. Wide macro shooting is possible at 11mm with an MOD of 0.15m (5.9") and maximum magnification ratio of 1:4. Its stunning close-range shooting performance enables creative use of perspective at the wide end. The lens also incorporates an AF drive system with an RXD (Rapid-eXtra-silent stepping Drive) stepping motor unit that is remarkably quiet. The 11-20mm accurately captures not only still images but also video. It is highly practical, with Moisture-Resistant Construction, Fluorine Coating, and other features designed for outdoor shooting, letting users easily enjoy the high image quality of this ultra wide-angle fast -aperture F2.8 lens under a range of conditions.
