Tamron 11-20mm f/2.8 Di III-A RXD Lens (Sony E)

Versatile Ultra Wide-Angle Zoom:

Designed for Sony E-mount APS-C-format mirrorless cameras, providing a 35mm equivalent focal length range of 16.5-30mm.

Bright and Constant f/2.8 Aperture:

Features a fast and constant f/2.8 maximum aperture, ensuring consistent brightness throughout the zoom range. This aperture setting allows for improved control over depth of field and enhanced low-light performance.

Optical Design:

Incorporates advanced optical elements, including one XLD (eXtra Low Dispersion) element, two LD (Low Dispersion) elements, and two glass-molded aspherical elements.

These elements work together to minimize chromatic aberrations, color fringing, and image distortion, resulting in improved clarity and color accuracy.

BBAR-G2 Coating:

Utilizes the BBAR-G2 (Broad-Band Anti-Reflection) Coating on lens elements to suppress internal reflections, flare, and ghosting. This coating enhances contrast and color fidelity, especially in challenging lighting conditions.

RXD Autofocus Motor:

Equipped with an RXD (Rapid eXtra-silent stepping Drive) autofocus motor, providing quiet, quick, and smooth focusing performance. This makes the lens suitable for both still photography and video applications.

Ultra Close Focusing:

Offers a minimum focusing distance of 5.9″ at 11mm, allowing for dynamic wide-angle macro imaging. This feature makes close objects appear larger and distant objects smaller. The f/2.8 aperture also produces a shallow depth of field with soft bokeh background details.

Weather-Sealed Construction:

Designed with moisture-resistant construction, making it suitable for use in inclement weather conditions.

Features a fluorine coating on the front lens element, providing protection against dust, dirt, and smearing.

Rounded Diaphragm:

Utilizes a rounded seven-blade diaphragm, contributing to a pleasing bokeh quality in out-of-focus areas.
