Tamron has unveiled their new 17-70mm f/2.8 Di III-A VC RXD zoom lens for Sony E-mount APS-C mirrorless cameras. The lens has a roughly 25-105mm full-frame equivalent field of view and is estimated to begin shipping in January next year.

In addition, the new Tamron zoom lens is priced at $799 and is now available to pre-order from B&H.

The new 17-70mm f2.8 (model B070) is the company’s first high-speed zoom lens for crop sensor mirrorless cameras. And according to Tamron, their new 17-70mm is “the first f2.8 high-speed zoom lens in the world for APS-C mirrorless cameras to achieve a 4.1x zoom ratio.”

This lens is gearing up to be a very suitable one-lens-for-all type of scenario for cameras like the Sony a6600 for example.

Compact and Lightweight Design for APS-C Mirrorless

The new measures 4.7 inches in length and weighs 18.5 oz (525g). Moreover, this compact size allows Tamron to keep the front filter diameter to 67mm, which is standard across their full-frame zoom lenses for Sony E mount. Such lenses include the popular 17-28mm f2.8, and the 28-75mm, in addition to newer additions such as the Tamron 28-200mm zoom, and the 70-180mm f2.8 telephoto.


Furthermore, the lens features compact and lightweight design and also has Image Stabilization. Or as Tamron calls – VC (Vibration Compensation) mechanism to minimize camera shake. In addition, Tamron’s VC mechanism leverages AI technology when shooting video.

Image Stabilization for Video with AI

Also, Tamron are claiming that this new Image Stabilization is said to employs some sophisticated algorithms “…and a dedicated, independently operating MPU all combine to superbly compensate for vibration.” 

This feature is meant to be used with cameras with built-in IBIS so as to enhance the overall image stabilization.

Support for Fast Hybrid AF and Eye AF

The new 17-70mm also features Moisture-Resistant Construction, a fluorine coating and as mentioned earlier shares a 67mm filter size as the Tamron full-frame zooms for Sony mirrorless cameras.

Furthermore, this lens is also compatible with advanced Sony camera features including Fast Hybrid AF and Eye AF

And as far as the optical formula, it includes the impressive 16 elements arranged in 12 groups. Of these, two are Aspherical GM (Glass Molded Aspherical) lens elements and one hybrid aspherical lens element. These elements are precisely arranged to maintain edge to edge image sharpness and fidelity.

Minimum Focusing Distance

And when it comes down to the focus distance, the new Tamron can focus down to a minimum of 19cm or (7.5 inches), which is substantially better than conventional standard zoom lenses for APS-C cameras.

On the 70mm telephoto end of the zoom range, the Tamron can focus on subjects located at a distance of at least 39cm (15.4 in). 

Pricing and Availability

The new Tamron lens is priced at $799 and is now available to pre-order from B&H. First shipments are expected to arrive in January 2021.
