The Tamron 28-75mm F2.8 DI III VXD G2 Nikon Z-mount – photographic lens was redesigned from the ground up, using the most advanced design expertise to develop an optical scheme consisting of 17 elements in 15 groups. With two optimally arranged LD (Low Dispersion) and GM (Glass Molded Aspherical) optical elements, optical aberrations are controlled to the highest possible degree. The image quality at full aperture has been significantly improved over that of the previous model, offering extremely high resolution throughout the entire zoom focal length range and over the entire frame area. The lens also offers the soft and beautiful bokeh effects characteristic of very bright lenses. The new Tamron 28-75mm F2.8 achieves extremely high performance when combined with high quality, high resolution digital cameras and has the same compact dimensions as its predecessor.

In addition, the Tamron 28-75mm sports a new design that will become the hallmark of TAMRON lenses to be introduced in the future. Changes to the surface texture of the zoom ring and focus ring improve grip and increase ease of use. The lens barrel surface is glossy black, much shinier than previous models. The increased abrasion resistance makes the lens more difficult to scratch and resistant to fingerprints. In addition, some internal parts have also been improved. These improvements result in smoother handling overall. Tamron has also adjusted the resistance and torque of the zoom ring to make its operation even smoother and more precise.
