Tamron announces 17-70mm F2.8 zoom lens for Sony APS-C mirrorless cameras

Tamron has announced a new lens for Sony APS-C cameras. The Japanese manufacturer of lenses has unveiled 17-70mm F2.8 Di III-A VC RXD lens for E-mount cropped sensor cameras. The new 17-70mm F2.8 is a standard zoom lens that will help camera users in taking close-up shots.

The lens boasts a fast maximum aperture across its focal range and is packed with Vibration Compensation (VC) for low-light photography. The company says its VC mechanism uses Artificial Intelligence technology when shooting video. The AI technology promises to work with cameras with and without in-body image stabilization. The VC system also uses a Dual Micro Processing Unit with a built-in Digital Signal Processor.

Whereas, the RDX in the name of the lens stands for Rapid eXtra-silent stepping Drive. It is compatible with many of the features that Sony builds into its cameras such as Fast Hybrid autofocus, Eye autofocus, and in-camera lens correction.

Tamron's latest 17-70mm F2.8 lens consists of 16 elements in 12 groups, including two glass moulded aspherical elements and one hybrid aspherical element. The latter most element helps in maintaining "high-resolution performance from edge to edge." It also has fluorine coating on the front element, and a 67mm filter. The lens features a moisture-resistant build as well.

The 17-70mm F2.8 has a focusing distance of 7.5-inch at 17mm, which Tamron says is superior to other similar zoom lenses on the market for APS-C format cameras. When zoomed to 70mm, the focusing distance expands to 15.4-inch.

Tamron 17-70mm F2.8 Di III-A VC RXD, which is compatible with Sony E-mount mirrorless APS-C cameras, will be out in mid-January, 2021. The release date is subject to change due to the novel coronavirus pandemic. The lens will debut in the United States for $799. However, the price and availability of Tamron's latest zoom lens in India is not known.

Speaking of more lenses that may debut next year, Canon is also planning to launch new super telephoto lenses reportedly. Canon already has a line of super telephoto lenses for mirrorless cameras which includes Canon RF 600mm F11 IS STM, and Canon RF 800mm F11 IS STM. Now, there are conjectures about Canon to introduce RF 400mm F11 IS STM lens which may complete a trilogy of super small super telephoto lenses.

Earlier, both the 800mm and 600mm F11 lenses were more of a conceptual lens from the company. But since the aforementioned super telephoto lenses are well-liked among camera users, the news of the launch of Canon 400mmlens can turn out to be true.
