Tamron 11-20mm f/2.8 Di III-A2 RXD Lens: Ultra-Wide Performance for Canon RF-Mount
The Tamron 11-20mm f/2.8 Di III-A2 RXD Lens is a dynamic, fast-aperture ultra-wide-angle zoom designed for Canon RF-mount APS-C mirrorless cameras. This compact and lightweight lens is particularly well-suited for landscape, astrophotography, and architectural shooting, offering a versatile 35mm equivalent focal length range of 18-32mm.

Bright Aperture and Exceptional Optics
Its constant f/2.8 maximum aperture provides consistent brightness throughout the zoom range, affording increased control over depth of field along with enhanced low-light performance. The optical design incorporates one XLD element, two LD elements, and two glass-molded aspherical elements. These work in concert to produce a highly corrected image with significantly reduced chromatic aberrations and color fringing, resulting in improved clarity and color accuracy. Individual elements also feature Tamron’s BBAR-G2 (Broad-Band Antireflection) Coating, which effectively suppresses flare and ghosting for greater contrast, even when working in backlit and harsh lighting conditions.

Responsive Autofocus and Unique Macro Capabilities
A responsive RXD (Rapid eXtra-silent stepping Drive) motor enables quick, near-silent autofocus performance, making it ideal for both stills and video applications.

This ultra-wide lens also unlocks powerful wide-angle macro shooting capability with a remarkably close minimum object distance of just 5.9″ at the widest end of the zoom range. This unique perspective makes near objects appear larger and distant objects smaller, creating dynamic and compelling close-up images. Additionally, the f/2.8 maximum aperture produces a shallower depth-of-field that results in beautifully soft bokeh background details. A rounded seven-blade diaphragm further contributes to this pleasing bokeh quality.

Durable and Reliable Construction
For peace of mind in challenging environments, the lens features moisture-resistant construction to protect it under inclement conditions. The front lens element is also treated with a fluorine coating to protect against dust, dirt, and smearing, making it easy to keep clean.
