Tamron has announced the development of a compact tele-zoom for full-frame Sony E-mount bodies: the 70-180mm F2.8 Di III VXD. The lens will be just 149mm (5.9″) long and will weigh in at 815g (1.8lbs), and it will use the same 67mm filters as the two other lenses in the series: the 17-28mm F2.8 and 28-75mm F2.8.
The 70-180 will offer ‘several’ specialized glass elements and will use the company’s VXD linear focus motor. The minimum focus distance is a relatively short 0.85 meters (33.5 inches). The lens will be sealed against dust and moisture, and will have a fluorine coating to repel oil and water from the front element.
Tamron says that the 70-180mm F2.8 Di III VXD will be available in Spring of next year.

Much-anticipated third model in its series of F/2.8 high-speed zoom lenses delivers superb optical performance with extremely quiet, fast focus
70-180mm F/2.8 Di III VXD (Model A056)
October 23, 2019, Commack, NY – Tamron announces the development of a new high-speed telephoto zoom lens for Sony E-mount full-frame mirrorless cameras, the 70-180mm F/2.8 Di III VXD (Model A056). Availability of this new zoom is planned for Spring 2020. The lens will be on display at the upcoming Photo Plus Expo in New York City this week and Salon de la Photo in Paris next month.
Developed under the concept of “making high-speed zoom lenses user-friendly,” Model A056 features a compact and lightweight design, an ideal match for full-frame mirrorless interchangeable lens cameras. The 67mm filter diameter is the same as all other Tamron lenses in this series. The optical design includes several specialized glass elements that contribute to the lens’s superb imaging performance and its very short 33.5 in MOD (Minimum Object Distance) expands overall versatility. The lens adopts Tamron’s newly developed VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism that produces a quiet, quick autofocus drive.
Other features that support a great shooting experience include a Moisture-Resistant Construction helpful for outdoor shooting and Fluorine Coating for easy maintenance. In addition, Model A056 is fully compatible with various camera-specific features including Fast Hybrid AF and Eye AF. This new model joins the 17-28mm F/2.8 Di III RXD (Model A046) and the 28-75mm F/2.8 Di III RXD (Model A036) and brings Tamron’s total of F/2.8 zoom lenses for full-frame mirrorless cameras to three.
