Tamron is Developing a 70-300mm f/4.5-6.3 for Nikon Z Mount

Tamron has announced the 70-300mm f/4.5-6.3 Di III RXD, the company’s first Z-mount system lens, as the thinnest and lightest telephoto zoom for full-frame mirrorless cameras.

The lens looks to be similar to the Sony E-mount 70-300mm f/4.5-6.3 Di III RXD, which was released in 2020, and shares many, if not all, of the design decisions found in that lens, including promises of being the “smallest and lightest” telephoto zoom for full-frame cameras. It also features the same optical structure of 15 elements in 10 groups, which Tamron claims is “precisely structured to minimise axial chromatic and other aberrations that are prone to develop with telephoto zoom lenses.”

Tamron claims that at 300mm, the design provides “excellent resolution” from edge to edge and produces crisp pictures across the zoom range owing to the company’s anti-reflection BBAR Coating.

The mirrorless lens is 5.9 inches long, has a maximum diameter of 77mm, and weighs 20.5 ounces. According to Tamron, the compact dimensions and light weight make it perfect for travel and allow for simple access to landscape and sports photography, as well as portraiture, bird photography, and “casual shots.”

Tamron’s Rapid eXtra-silent stepping Drive (RXD) powers the lens autofocus, which the firm claims enables highly rapid and accurate autofocus and lets users to retain tack-sharp focus on continually moving scenes often captured with telephoto zoom lenses.

The lens will be compatible with Tamron’s Lens Utility software and allows users to update the lens firmware after purchase. It is also moisture resitant.

The price of the lens will be Rs. 63,000 and it will launched on September 29, 2022.
