Tamron has announced the development of what it claims is the `smallest and lightest` telephoto zoom for Sony E-mount: the 70-300mm F4.5-6.3 Di III RXD.
This focal range isn`t new to Tamron, but this is the first 70-300 developed for full-frame mirrorless bodies. The lens is weather-sealed and its focus group is driven by an `RXD` stepping motor. The diameter of the lens is 77mm (3`) while it weighs in at 544g (19.2oz).
The 70-300mm F4.5-6.3 Di III RXD is expected to ship this fall.

Tamron Announces the Development of the World`s Smallest and Lightest Telephoto Zoom Lens for Sony E-mount Full-Frame Mirrorless Cameras
70-300mm F/4.5-6.3 Di III RXD (Model A047)
August 3, 2020, Commack, NY - Tamron announces the development of a new telephoto zoom lens for Sony E-mount full-frame mirrorless cameras, the 70-300mm F/4.5-6.3 Di III RXD (Model A047). The lens is planned to launch in Fall 2020.
While Tamron has manufactured many popular telephoto zoom lenses that extend to 300mm for DSLR cameras, the new 70-300mm F4.5-6.3 is the first model designed for full-frame mirrorless cameras. Developed with the concept of bringing the joy of easy telephoto shooting to photographers everywhere, it`s the world`s smallest and lightest 70-300mm zoom lens at 5.8 in., 19.2 oz. and maximum diameter of 77mm, and delivers exceptional image quality.
Its Moisture-Resistant Construction provides greater protection when shooting outdoors and the lens shares the 67mm filter diameter common to all members of Tamron`s lens series for full-frame mirrorless cameras. The lens also takes full advantage of in-camera features, including Sony`s Fast Hybrid AF and Eye AF that support a fantastic shooting experience. The 70-300mm F4.5-6.3 is a highly practical lens that makes the excitement of telephoto shooting easier than ever before across a diverse range of shooting styles including landscapes, sports and other athletic events, wildlife, portraits, and more.
