The new ultra wide-angle zoom lens features a compact and lightweight design
At a weight of 420g and an overall length of 99mm, with no barrel extension whilst focusing or zooming, Tamron’s new lens lends itself well to photographers with limited space, such as those who travel often.
The 17-28mm RXD offers a large f/2.8 aperture throughout the entire zoom range and delivers edge-to-edge high resolution and contrast. The lens combines ultra wide-angle focal length with a large, constant f/2.8 aperture, and has a minimum object distance of 19cm at the wide-angle end.
The new lens’s autofocus drive system is powered by the RXD (Rapid eXtra-silent stepping Drive) AF motor unit that enables high-speed, high-precision and quiet operation when shooting both still photography and video.
Additionally, the lens features a moisture-resistant construction with a hydrophobic fluorine coating to repel fingerprints, marks and dirt. The 17-28mm RXD is also fully compatible with various camera-specific features including Fast Hybrid AF and Eye AF.
