Tamron has announced the development of a new 70-300mm f/4.5-6.3 Di III RXD telephoto zoom lens for Sony full-frame E-mount.

Tamron is claiming that it will be “the world’s smallest and lightest” 70-300mm zoom lens by measuring 5.8 inches (148 mm) long, 3.03 inches (77 mm) in diameter, and weighing just 19.2 oz (545 grams).

The lens shares the same 67mm filter thread size as Tamron’s other E-mount lenses, so you can easily share filters and save a small fortune! The lens is also moisture-resistant to help protect it from the elements.

The lens features an RXD stepping motor, which is the same motor that can be found in the Tamron 28-75mm f/2.8 (Amazon | B&H Photo) and the latest 28-200mm f/2.8-5.6 (Amazon | B&H Photo).

Like Tamron’s other lenses for Sony E-mount, Tamron has not included stabilization in the lens, instead leaving in-camera stabilization (IBIS) to do the job. Leaving out stabilization helps Tamron to keep the size, weight and likely the cost down, but in a 300mm lens this is probably starting to push the limits of what people will be able to handhold unless very fast shutter speeds are used.

The lens is planned to go on sale this fall and the price is yet to be announced, but I’d expect it to be comfortably under $1,000 if they want to steal some sales away from Sony’s FE 70-300mm f/4.5-5.6 G OSS lens (Amazon | B&H Photo) that does include stabilization.

About Timothy Mayo

I love shooting wildlife the most but will happily point my camera at pretty much anything. I started Alpha Shooters in 2017 to share my own photographic journey and experiences shooting with Sony Alpha. The site has since evolved into a popular community and resource. You can also find out more about my story here or follow me on Instagram if you wish. I also have a YouTube Channel but haven't published much content over the past year due to spending more time changing smelly nappies and also launching our community forums. However, I do plan to get back to creating content for YouTube in 2021!
