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

Tamrones Dynamic 11-20mm F / 2.8 Di III-A2 RXD Lens is a fast aperture ultra-wide-angle zoom lens for Sony E-mount APS-C mirrorless cameras. It boasts the world's first f / 2.8 maximum aperture for mirrorless Sony E-mount APS-C in this category and has a compact and lightweight design. This ultra-wide lens is especially suitable for landscape photography, astrophotography and architecture. Its bright constant f / 2.8 maximum aperture complements this range and provides greater control over depth of field along with improved 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 color clarity and accuracy. Individual elements also feature Tamron's BBAR coating, which suppresses flare and ghosting for increased contrast when working in harsh and backlit conditions. A responsive RXD stepper drive motor enables fast and near-silent autofocus performance to accommodate still images and video. The minimum distance to the subject is only 5.9 "at the widest end of the zoom range, enabling powerful wide-angle macro shooting with a unique perspective that makes nearby objects appear larger and distant ones In addition, the f / 2.8 maximum aperture produces a shallow depth of field that creates soft bokeh background details. The moisture-resistant construction protects the lens in inclement conditions, and a fluorine coating on the element Front lens protects against dust, dirt, and smudges. Nearly silent autofocus performance to accommodate still images and video. Minimum distance to subject is only 5.9 "at widest end of zoom range , enabling powerful wide-angle macro shooting capabilities with a unique perspective that makes nearby objects appear larger and distant objects smaller. Additionally, the f / 2.8 maximum aperture produces a shallow depth of field that creates soft bokeh background details. The moisture-resistant construction protects the lens in inclement conditions, and a fluorine coating on the front lens element protects against dust, dirt, and smudges. Near-silent autofocus performance to accommodate still images and video.

The moisture-resistant construction protects the lens in inclement conditions, and a fluorine coating on the element Front lens protects against dust, dirt and smudges and smaller distant objects. Additionally, the f / 2.8 maximum aperture produces a shallow depth of field that creates soft bokeh background details. Moisture protects the lens in harsh conditions, and a fluorine coating on the front lens element protects against dust, dirt, smudges, and smaller distant objects. Additionally, the maximum aperture of f / 2.8 pr produces a shallow depth of field that creates soft bokeh background details. The moisture-resistant construction protects the lens in harsh conditions, and a fluorine coating on the front lens element protects against dust, dirt, and smudges.
Versatile ultra-wide-angle zoom for Sony E-mount APS-C format mirrorless cameras with a 35mm equivalent focal length range of 17-30mm.
Bright and constant f / 2.8 maximum aperture provides 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 to improve clarity and color accuracy.
A BBAR-G2 (broadband anti-reflection) coating has been applied to the lens elements to suppress internal reflections, flare and ghosting for higher contrast and color fidelity.
The RXD (Rapid eXtra-silent stepping Drive) autofocus motor offers surprisingly quiet, fast and smooth focusing performance to suit both still and video applications. Supports the direct manual focus function of Sony and Eye AF on enabled cameras, and full-time manual focus override is available.
The minimum focusing distance of 5.9 "to 11mm allows you to explore dynamic wide-angle macro images, making nearby objects appear larger and distant objects smaller. In addition, using the maximum aperture f / 2 , 8 produces a shallow depth of field with a soft bokeh background.
Designed and constructed with a moisture resistant construction for use in harsh conditions, plus a fluorine coating on the front lens element to protect against dust, dirt and smudges.
The rounded seven-blade diaphragm contributes to pleasant bokeh quality.
