The manufacturer warned that due to the spread of COVID-19, the start of deliveries may be delayed.
As expected, Tamron introduced the 70-180mm F / 2.8 Di III VXD (Model A056) lens, which the Japanese manufacturer announced the development of last September.
A telephoto lens with a constant maximum aperture is designed for full-frame mirrorless cameras with Sony E mount. Its sales should begin on May 14, 2020, at a recommended price of $ 1,199. However, the manufacturer makes a reservation that due to the distribution of COVID-19, deliveries may be delayed.
The lens description has a compact and lightweight design and compatibility with filters with a diameter of 67 mm – in this regard, the new lens is similar to the previously released models 17-28mm F / 2.8 (Model A046) and 28-75mm F / 2.8 (Model A036). Silent and fast automatic focusing is provided by a system with two linear VXD drives (Voice-coil eXtreme-Torque Drive). The lens is weatherproof and its front element has a coating that repels moisture and dirt.
