After the initially leaked image and specs, Tamron has now officially announced the new zoom lens for Sony E-mount. The Tamron 70-300mm f/4.5-6.3 Di III RXD is in the works, but it looks like we won’t have it in our hands for a while longer, as the company has only announced the development of the lens for now.
The 70-300mm F/4.5-6.3 Di III RXD will be “the world’s smallest and lightweight telephoto zoom lens for Sony E-mount.” As mentioned in the leaked information, the lens is 148mm (5.8 in) long, weighs 545g (19.2 oz), and has a maximum diameter of 77mm. This is also the first telephoto zoom that Tamron is designing for full-frame cameras.
The company still hasn’t released full specs, but here are the main features:
The world’s smallest and lightest size brings you the joy of easy telephoto shooting.
Superb optical performance including high image quality and aberration correction.
The AF drive system is powered by the RXD stepping motor unit for high-speed, high precision and quiet operation.
Moisture-Resistant Construction contributes to a comfortable, user friendly photographic experience.
There isn’t much new information Tamron has revealed after the recent leak. However, we do know the approximate launch date. The company plans to launch the 70-300mm f/4.5-6.3 Di III RXD in the fall of 2020. I think it’s not really that far from now, as September is just around the corner. But as soon as we know more, we’ll keep you posted.
