Tamron Announces 70-300mm f/4.5-6.3 Di III RXD Full-Frame Lens for Sony E-Mount

Today, Tamron has announced its latest full-frame E-mount lens, the 70-300mm f/4.5-6.3 Di III RXD. Not only is it quite thrifty at $549, it’s also the smallest and lightest telephoto zoom lens available for the Sony mount.

Measuring in at 5.80 inches in length with a 3.03 maximum diameter, the new 70-300mm weighs just 1.2 pounds. Like the other Tamron full-frame mirrorless lenses, it has a 67mm filter thread for compatibility across the range. Used on a crop sensor camera body like the Sony a6600, the 70-300mm turns into an effective 105-450mm lens.

Inside, the lens houses 15 elements in 10 groups, including one low dispersion element and Broad-Band Anti-Reflection coating for optimized image quality. The lens features a moisture-resistant construction and has a seven-bladed circular aperture.

Tamron promises great performance with Sony’s various autofocus features such as Real-time Tracking, Eye AF, and DMF through the utilization of its RXD stepping motor. According to Tamron, the 70-300mm “can be used discreetly in concert halls and other situations that require low noise levels, and for video recording.” It has a close focusing distance of 31.5 inches at the wide end and 59.1 inches at the telephoto end.

The Tamron 70-300mm f/4.5-6.3 Di III RXD will begin shipping on October 29, 2020.
