KEY FEATURES:

You’ll be amazed from the very first shot: The world's first1 fast-aperture F2.8 ultra wide-angle zoom lens for mirrorless invites new experiences

Capture dynamic images with a fast-aperture ultra wide-angle zoom lens: Covering focal lengths from 11-20mm (a full-frame equivalent of 16.5-30mm), this ultra wide-angle lens for APS-C mirrorless cameras features a maximum aperture of F2.8 and allows users to fully enjoy the distinctive depth-of-field and unique perspective provided by an ultra wide-angle lens.

A design so compact and lightweight, it’s hard to believe it’s an ultra wide-angle lens: The lens was designed to be exceptionally compact and lightweight, an ideal match with APS-C mirrorless cameras. It has an overall length of 86.2mm (3.4 in) 3, and weighs only 335g (11.8 oz).

Enjoy the outstanding optical performance of the TAMRON 11-20mm F2.8: The 11-20mm F2.8 is a high-resolution lens that focuses on superb image quality as a fast-aperture ultra wide-angle zoom. The optical construction includes 12 elements in 10 groups. High resolution performance is maintained across the entire frame with the well-balanced arrangement of two GM (Glass Molded Aspherical) lens elements. Two LD (Low Dispersion) and one XLD (eXtra Low Dispersion) lens elements are used to suppress the chromatic aberrations that tend to occur when shooting at the wide-open aperture of fast-aperture lenses.

Indulge in the exciting world of wide-angle macro with an MOD of 0.15m: The MOD is just 0.15m (5.9 in) at the widest end. This extreme close-range shooting performance allows you to get as close to a subject as you like. The maximum magnification ratio is 1:4 (an astonishing feat for an ultra wide-angle lens) and it unlocks powerful wide-angle macro shooting utilizing the unique perspective that makes near objects look larger and distant objects smaller.

Explore a wide variety of situations by combining two lenses in TAMRON's series of fast-aperture zooms for APS-C mirrorless cameras: By combining the 11-20mm F2.8 and its balance of excellent portability and high image quality with the 17-70mm F/2.8 Di III-A VC RXD (Model B070) (sold separately), these two lenses cover an extreme range of focal lengths from 11mm to 70mm (a full-frame equivalent of 16.5mm to 105mm) with a fast, wide-open aperture of F2.8. The combined weight of the two lenses is only approximately 860g (30.3 oz).

High performance autofocus operates quietly and accurately captures subjects when shooing both still and video: The AF drive on the 11-20mm F2.8 includes an RXD stepping motor unit to help you stay focused on the action. RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear.
