A few days ago, Tamron announced that the full-frame telephoto zoom lens for Nikon Z mount - 70-300mm F / 4.5-6.3 Di III RXD (model A047) new product on September 29, 2022, officially listed on the day. Now, this lens has been pre-sold on JD.com, priced at 4,990 yuan.
The optical design of this lens uses Tamron's new design technology to conduct in-depth simulation calculations, and successfully achieves the coexistence of compactness and high image quality. The lens structure of 15 elements in 10 groups is optimally equipped with LD (Low Dispersion) low-dispersion lenses, which have a good suppression effect on various aberrations such as axial chromatic aberration that are easily generated on telephoto lenses.
According to Tamron, this lens is specially designed for mirrorless cameras. By setting the F value of the telephoto end to F6.3, the lens achieves a length of 150.3mm, a maximum diameter of φ77mm, and a weight of 580g. In addition, the main positions of each mechanical movable part and joint part of the lens barrel are equipped with anti-splash seals to provide more protection for outdoor shooting.
