(President & CEO: Shiro Ajisaka; Headquarters: Saitama City), a leading manufacturer of optics for diverse applications, announces the development of a new telephoto zoom lens for Sony E-mount full-frame mirrorless cameras, the 70-300mm F/4.5-6.3 Di III RXD (Model A047).

While Tamron has manufactured many popular telephoto zoom lenses that extend to 300mm for DSLR cameras, the newly released 70-300mm F4.5-6.3 is the first model designed for full-frame mirrorless cameras. Developed with the concept of bringing the joy of easy telephoto shooting to photographers everywhere, it’s the world’s smallest and lightest* 70-300mm zoom lens at 148mm (5.8 in), 545g (19.2 oz) and maximum diameter of 77mm, and delivers exceptional image quality.

Its Moisture-Resistant Construction provides greater protection when shooting outdoors and the lens shares the 67mm filter diameter common to all members of Tamron’s lens series for full-frame mirrorless cameras. The lens also takes full advantage of in-camera features, including Sony’s Fast Hybrid AF and Eye AF that support a fantastic shooting experience. The 70-300mm F4.5-6.3 is a highly practical lens that makes the excitement of telephoto shooting easier than ever before across a diverse range of shooting styles including landscapes, sports and other athletic events, wildlife, portraits, and more.
