How to Use the Tamron 11-20mm f2.8 Di III-A RXD Lens

Advanced Optical Performance

Tamron has engineered the 11-20mm f2.8 Di III-A RXD lens for Canon RF-mount with a highly sophisticated optical design to meet the demands of professional users. Its construction features 12 elements in 10 groups, including two GM (Glass Molded Aspherical) elements, delivering exceptional resolution and edge-to-edge sharpness throughout the zoom range.

Additionally, the lens incorporates one XLD (eXtra Low Dispersion) and two LD (Low Dispersion) elements to suppress chromatic aberrations effectively, ensuring superior image quality. The BBAR-G2 (Broad-Band Anti-Reflection Generation 2) coating minimises ghosting and flare, even in challenging backlit conditions, for consistent and high-contrast performance.

Versatile and Flexible

The lens offers a fast, constant f2.8 aperture across its zoom range, providing excellent low-light capability and precise depth-of-field control. Designed specifically for Canon RF-mount APS-C mirrorless cameras, it ensures seamless compatibility for versatile shooting.

With a Minimum Object Distance (MOD) of just 15cm at the 11mm focal length and 24cm at 20mm, this lens supports a maximum magnification ratio of 1:4. This allows users to capture wide-angle macro images with creative close-up perspectives, making it suitable for landscapes, interiors, astrophotography, and detailed macro work.

Precision Focus

Tamron has equipped this lens with the Rapid eXtra-silent Drive (RXD), a stepping motor designed for precise and quiet autofocus performance. The actuator directly controls the motor’s rotational angle, eliminating the requirement of a reduction gear. Combined with the position-detecting sensor, this system delivers highly accurate and responsive autofocus, making it ideal for photography and videography involving dynamic or fast-moving subjects.
