Commack, NY—Tamron launched the Tamron 70-300mm F4.5-6.3 Di III RXD (model A047) lens for the Nikon Z-mount system. The telephoto zoom lens is for full-frame mirrorless cameras. In addition, the Z-mount lens has a suggested retail price of $699.
The telephoto zoom lens “combines the world’s smallest size and lightest weight together with high image quality based on Tamron’s concept of ‘all photographers should enjoy easy and comfortable telephoto photography,’” the company announced.
The lens measures 5.9 inches long with a maximum diameter of 77mm and a weight of 20.5 ounces.
With the new lens, photographers can experience the compression effects and limited depth-of-field unique to a real telephoto lens. The lens is also an option for users who want to reduce the weight of their luggage or lighten their load in the field. In addition to landscapes and sports, photographers can enjoy telephoto shooting for a broad array of subjects, like portraits, birds and casual snaps.

Specifically for mirrorless cameras, it offers an f/6.3 aperture at the telephoto end.
Furthermore, based on simulations utilizing the latest design technologies, its optical design balances its compact size and high image quality. The optical construction includes 15 elements in 10 groups. An LD (low dispersion) lens element is precisely arranged to suppress axial chromatic and other aberrations likely to occur with telephoto zoom lenses.
Moreover, Tamron says that at 300mm, a commonly used telephoto focal length, the design delivers excellent resolution from edge-to-edge. The new zoom also creates crisp, clear images throughout its zoom range due to Tamron’s antireflection BBAR coating.
In addition, the lens’s AF drive incorporates a sensor that detects the position of the lens while the RXD motor unit (rapid eXtra-silent stepping drive) helps deliver optimized AF control. As a result, the lens achieves fast, accurate autofocus operation. It also enables photographers to maintain sharp focus on continuously moving subjects. What’s more, thanks to quiet autofocusing, the lens can be used discreetly in situations that require low noise levels, as well as for video shooting. 
For worry-free outdoor use, there are seals located at the lens mount area and other critical locations to deter infiltration of moisture and/or rain—thus affording moisture-resistant construction. This feature provides an additional layer of protection when shooting under adverse weather conditions.
Tamron Lens Utility Software
Additionally, with this Nikon Z-mount-compatible version, photographers can employ the dedicated Tamron Lens Utility software that Tamron developed in-house. They can do so via an optional Tamron connection cable. This enables users to easily update the lens to the latest firmware themselves, without going through the camera. On the firmware information screen, users can confirm that their lens has the latest version as well as perform an update if newer firmware is available.
