Tamron 11-20mm f/2.8 Di III-A RXD Lens (Canon RF)

Tamron's dynamic 11-20mm F/2.8 Di III-A2 RXD Lens is a fast-aperture ultra-wide-angle zoom lens for Canon RF-mount APS-C mirrorless cameras. It features a fast and constant f/2.8 maximum aperture and has a compact and lightweight design. This ultra-wide lens suits landscape, astrophotography, and architectural shooting. Its bright f/2.8 aperture complements this range and affords increased control over field depth and enhanced low-light performance.

The optical design incorporates one XLD element, two LD elements, and two glass-molded aspherical elements to produce a highly corrected image with reduced chromatic aberrations and color fringing for improved clarity and color accuracy. Individual elements also feature Tamron's BBAR coating, which suppresses flare and ghosting for greater contrast when working in backlit and harsh lighting conditions. A responsive RXD stepping drive motor enables quick, near-silent autofocus performance to suit stills and video.

The minimum object distance is just 5.9" at the widest end of the zoom range, unlocking powerful wide-angle macro shooting capability with a unique perspective that makes near objects look larger, and distant objects smaller. Additionally, the f/2.8 maximum aperture produces a shallower depth-of-field that creates soft bokeh background details. Moisture-resistant construction protects the lens under inclement conditions, and a fluorine coating on the front lens element protects against dust, dirt, and smearing.

Versatile ultra wide-angle zoom for Canon RF-mount APS-C-format mirrorless cameras with a 35mm equivalent focal length range of 18-32mm. Bright, constant f/2.8 maximum aperture affords consistent brightness throughout the zoom range and offers improved control over depth of field.

XLD (eXtra Low Dispersion), LD (Low Dispersion), and GM (Glass-Molded Aspherical) elements greatly reduce color fringing, chromatic aberrations, and image distortion throughout the zoom range for improved clarity and color accuracy.

BBAR-G2 (Broad-Band Anti-Reflection) Coating has been applied to lens elements to suppress internal reflections, flare, and ghosting to achieve greater contrast and color fidelity.

RXD (Rapid eXtra-silent stepping Drive) autofocus motor delivers impressively quiet, quick, and smooth focusing performance to suit both still and video applications.
