Description
Get closer to your subject. As close as 0.11m.
One of the key features that makes this lens so exciting is its amazing ability to shoot close-ups. With this lens, you can get closer to an object than you’d ever imagined. At the 0.11m (4.3 in) MOD, the lens achieves its maximum magnification ratio of 1:2. You’ll never again be frustrated because you cannot get close to an object while shooting. This remarkable performance allows users to create compositions that exploit dramatic perspective (closer subjects are larger, and distant ones are smaller) and that are unique to wide-angle lenses. By getting close to an object, you can produce a one-of-a-kind photo and leverage the beautifully blurred background bokeh.
Focal length: 20mm Exposure: F/2.8 1/500sec ISO 100
The extreme portability enhances the limitless versatility of the lens
Take it with you anywhere. This lens travels as well as it performs. And because it’s matched to lightweight full-frame mirrorless cameras, your entire system becomes light, fast and nimble. It has a very compact body, weighing just 220g (7.8 oz) and an overall length of 64mm (2.5 in). It’s comfortably portable, highly maneuverable and amazingly easy to use and compose. Because the overall length does not change when focusing, you can get as close to an object as you need to without fear of accidentally bumping the front element. The lens has the same 67mm filter diameter as the other members of the series of Tamron high-speed lenses for Sony E-mount cameras. So you can swap filters (like polarizers), lens caps and other accessories for convenience. Who says great things can’t come in small packages?

The Exterior
Ultra wide-angle is dramatically creative
This lens provides outstanding optical performance and overall image quality, characteristics relentlessly demanded from a prime, fixed focal lens. The expert arrangement of the LD and GM specialized glass elements greatly controls aberrations, including chromatic aberrations. Tamron’s proprietary BBAR (Broad-Band Anti-Reflection) Coating reduces ghosting and flare, which can otherwise occur when taking a photo against the sun. Moreover, leveraging your camera body’s features* it delivers, throughout the frame, high resolution performance that maximizes the benefits of the latest high-megapixel cameras. Whether shooting on the street, full-scale landscapes or architectural photography, this lens delivers exceptionally crisp, colorful and beautiful images and helps you fulfill your creative ambitions.
*When shooting with the camera’s lens correction function enabled.
