Popular budget lens maker Tamron has just announced they are working to bring a new full-frame Sony FE zoom to market. The new Tamron 70-300mm f4.5-6.3 Di III RXD for Sony FE is said to be the ‘lightest telephoto zoom’ in its class (at least at the time of this development announcement).
As you know, Tamron has been making some fantastic zoom lenses for Sony full-frame mirrorless cameras as of late. These include the ‘trio’ of Tamron 17-28mm f2.8, Tamron 28-75mm f2.8, and the excellent Tamron 70-180mm f2.8 (pictured below).

And while Tamron is keeping their cards close to their chest, the development announcement press releases does give us a few details.
Weather-Proof and Fast Hybrid AF and Eye AF Support
The new lens will have a ‘Moisture-Resistant Construction’ which is expected from this class lens for protection against the elements when shooting outdoors where it will be used most, if not all, of the time.
And in keeping up with the rest of their mirrorless zoom lenses for Sony FE, the new 70-300mm will feature the same 67mm filter diameter. This will help you share filters across the range without the need for step-up or step-down rings.
Furthermore, Tamron say their new long-telephoto will take full advantage of in-camera features, including Sony’s Fast Hybrid AF and Eye AF.
In addition, Tamron also say the new lens will feature an AF drive system powered by the RXD stepping motor unit for high-speed, high-precision and quiet operation.
