Tamron AF 11-20/2.8 Di III-A RXD to Sony E-mount-10 years CH warranty

The 11-20mm F/2.8 is an ultra-wide-angle zoom lens par excellence. The 11mm focal length (KB equivalent 16.5mm) allows for outstandingly dramatic perspectives with its wide field of view, while 20mm (KB equivalent 30mm) is ideal for spontaneous snapshots, for example in reportage or street photography. Despite its consistent F/2.8 speed, the lens is compact and lightweight - making it wonderfully practical.

The 11-22mm F/2.8 measures just 86.2mm in length and weighs in at a mere 335g. So for an ultra-wide-angle zoom lens, it's remarkably compact and lightweight. Combined with an APS-C system camera, it forms a perfectly balanced, handy unit for photo and video shooting that is always at hand and can also be used optimally on a lightweight tripod or with a gimbal.

The optical construction of the 11-20mm F/2.8 includes 12 elements in 10 groups. Two special GM (Glass Molded Aspherical) lenses ensure uniformly high resolving power across the entire image area. One XLD (eXtra Low Dispersion) and two LD (Low Dispersion) elements also provide effective correction of optical aberrations, resulting in sharp images with natural high-intensity colors. The lens surfaces are coated with the BBAR-G2 anti-reflective coating (Broad-Band Anti-Reflection Generation 2), which reduces ghost images and reflections to a minimum. Even backlit shots are characterized by high brilliance and maximum detail reproduction.

The shortest distance setting of the 11-20mm F/2.8 is 0.15 m at 11 mm and 0.24 m at 20 mm focal length. The lens thus offers better wide-angle close-up shooting capabilities than other ultra-wide-angle zoom lenses. At 11 mm, a maximum magnification of 1:4 is achieved, allowing for impressive close-ups with a dramatic gradation of scale. The large aperture thereby allows attractive focus-blur effects with very expressive bokeh.

The 11-20mm F/2.8 is the ideal complement to the 17-70mm F/2.8 Di III-A VC RXD (model B070). Together, this zoom lens duo for mirrorless APS-C cameras with Sony E-mount weighs only about 860g. Combined, they cover the focal length range of 11 mm to 70 mm (KB equivalent 16.5 mm to 105 mm) with a consistently high speed of F/2.8. Both lenses drastically reduce the weight and size of camera equipment without sacrificing quality. In addition, like virtually all Tamron lenses for Sony E-mount, both have filter size (Ø 67 mm). This means that the same polarizing and gray filters as well as lens caps can be used on all lenses in the series.
