Tamron has a long history of manufacturing telephoto zoom lenses extending to 300mm for DSLR cameras, and the new 70-300mm F4.5-6.3 is the first model designed for full-frame mirrorless cameras. Developed with the concept of making telephoto shooting easier for photographers around the world, it is the world’s smallest (148mm) and lightest (545g) 70-300mm telephoto zoom lens1, delivering exceptional image quality.

Its moisture-resistant construction provides added protection when shooting outdoors, and the lens shares the 67mm filter diameter common across Tamron's full-frame mirrorless lens series. The lens also takes full advantage of all the camera's features, including Sony's Fast Hybrid AF and Eye AF, providing a fantastic shooting experience. The 70-300mm F4.5-6.3 is a practical telephoto lens that is easy to use in a wide range of photographic styles, including landscapes, sports and other event photography, wildlife, portraits, and more.

Tamron developed a special design for its mirrorless-compatible lenses, achieving a compact size and an aperture of F/6.3 at the telephoto end. The maximum diameter is 77mm, the lens is only 148mm long, and it weighs just 545g. This makes the 70-300mm F4.5-6.3 the world's smallest and lightest telephoto zoom for full-frame mirrorless cameras. Compatible with popular Sony E-mount cameras, it has been developed for a lighter photographic experience in the 300mm telephoto range on full-frame cameras.

In addition, the AF system of this 70-300mm incorporates the exceptionally quiet RXD (Rapid eXtra-silent Stepping Drive) stepping motor. Compatible with Sony E-mount cameras, including in-body stabilizer and eye AF, this telephoto zoom allows you to comfortably enjoy the high speed and precision required for these focal lengths, even when shooting handheld.

Enjoy the experience of zooming into subjects and the unique perspectives offered by telephoto lens photography like never before. Ideal for landscapes, sports, birds, and wildlife, as well as bringing subjects closer in portraits or street scenes. This lens gives you more possibilities when taking your photographs.

With an ultra-lightweight design as a priority, Tamron has created a compact telephoto zoom lens that makes zoom photography at 300mm simple and fun. The excellent optical design is based on rigorous simulation tests, employing cutting-edge design technologies. As a result, Tamron has achieved the perfect balance between light weight (545g) and compact size (148mm length), including a maximum diameter of 77mm, without sacrificing image quality.

The optical design features 15 elements arranged in 10 groups, with an LD (Low Dispersion) lens element to suppress axial chromatic aberrations and other aberrations typical of telephoto zoom lenses. At 300mm, a common focal length for telephoto zoom lenses, this lens delivers excellent edge-to-edge resolution. Overall, the optical construction is extremely efficient (which also contributes to its light weight). Additional technologies, such as Tamron's proprietary BBAR (Broad-Band Anti-Reflection) coating, achieve incredible anti-reflection properties, combine to allow the photographer to capture extremely clear and sharp images throughout the entire zoom range. While the lens features an advanced design with excellent central image quality, depending on the situation, optical performance can be further enhanced by employing the lens correction features found on Sony cameras.

With the introduction of this lens, all photographers—from first-time users of telezoom lenses to seasoned professionals looking for a lightweight, compact telephoto zoom—can comfortably enjoy the benefits of this powerful and versatile zoom without worrying about size or weight. Photographers shooting with in-camera image stabilization or using a tripod can reduce the burden on their equipment. Furthermore, the 70-300mm F4.5-6.3 maintains strong imaging performance even when used with Sony E-mount cameras with APS-C sensors, which are smaller than full-frame sensors (e.g., the Sony α6500), allowing these users to enjoy telephoto zoom photography at an even longer focal length, as 300mm would be approximately equivalent to 450mm.

The AF system incorporates a sensor that detects the exact position of the lens, while the RXD motor adjusts the AF optimally. This results in precise, ultra-fast, and consistent autofocus. Constantly moving subjects are always captured in focus in both photos and videos, even at zoom and telephoto positions. Focus adjustment is performed so quietly that there is virtually no noise during recording, making it an ideal lens for concert halls and other situations where noise-free shooting is required. Finally, the compact size of the RXD AF system is the main reason Tamron has managed to design such a lightweight and small lens.

The 70-300mm F4.5-6.3 shares the same 67mm filter diameter as Tamron's other full-frame mirrorless lenses. By combining several of these lenses for a job, you can interchange filters (such as PL, ND, etc.) and lens caps, significantly minimizing costs and making all your gear easier to transport and manage.
