Built with Mirrorless in Mind The new 11-20mm F2.8 zoom is the world's first ultra wide-angle zoom lens for APS-C mirrorless cameras that features a maximum aperture of F2.8 throughout the zoom range. Despite its large F2.8 aperture, the lens is very small at just 3.4" long and feels perfectly balanced attached to a compact APS-C mirrorless camera body.
The Exciting World of Wide-Angle Macro At the 11mm ultra wide-angle end, the lens exhibits stunning close-range shooting performance, achieving a MOD (Minimum Object Distance) of 5.9" and a maximum magnification ratio of 1:4. This feature invites wide-angle macro shooting that exploits the creative effects of naturally occurring distortion that only ultra wide-angle lenses can provide.
	Extra Protection It is protected by Moisture-Resistant Construction and Fluorine Coating for confidence when shooting outdoors. Its 67mm filter size is identical to Tamron's 17- 70mm F/2.8 Di III-A VC RXD (Model B070) standard zoom lens for APS-C mirrorless cameras and Tamron’s series of lenses for full-frame mirrorless cameras that fit nicely on APS-C cameras as well.
Compact and Light Weight Design Compatible with many of the functions that Sony builds into its cameras, including Fast Hybrid AF and Eye AF, the lens is packed with highly practical features that support comfortable shooting and enable photographers to enjoy the superb image quality of this ultra wide-angle, large F2.8 aperture lens.
