Covering focal lengths from 11-20mm (equivalent to 16.5-30mm in full-frame format), this ultra wide-angle lens for Sony E-mount APS-C achieves a maximum aperture of F2.8 and allows users to fully enjoy the soft bokeh effects. Enjoy a higher degree of photographic freedom than ever before, such as taking regular snapshots at the 20mm end, and challenging yourself to take powerful ultra wide-angle shots at the wide end – all while enjoying the easy handling and the advantages that fast-aperture lenses offer.
The minimum focusing distance of 5.9" at 11mm makes it possible to explore dynamic wide-angle macro imaging, making close objects appear larger and distant objects smaller. Additionally, using the f/2.8 maximum aperture produces a shallow depth of field with soft bokeh background details.
Low light, worry not!
Bright, constant f/2.8 maximum aperture affords consistent brightness throughout the zoom range and offers improved control over depth of field.
Super compact design
The lens was designed to be exceptionally compact and light weight, an ideal match with Sony E-mount APS-C mirrorless cameras. It has an overall length of 86.2mm (3.4 in), and weighs 335g (11.8 oz). Imagine a lens so small and light that it is hard to believe it is a full-fledged fast-aperture ultra wide-angle zoom. You can concentrate on shooting without worrying about bulk or weight. When used with a compatible Sony E-mount APS-C mirrorless camera body, you will enjoy carefree handheld shooting of still images, or even find it easy to shoot video using a compact tripod or gimbal.
Outstanding optical performance
The 11-20mm F2.8 is a high-resolution lens that focuses on superb image quality as a full-fledged fast-aperture ultra-wide-angle zoom. The optical construction includes 12 elements in 10 groups. High resolution performance is maintained across the entire frame with the well-balanced arrangement of two GM (Glass Molded Aspherical) lens elements. Two LD (Low Dispersion) and one XLD (eXtra Low Dispersion) lens elements are used to suppress the chromatic aberrations that tend to occur when shooting at the wide-open aperture of fast-aperture lenses.
