Lens Overview
Zoom into the world of telephoto
The TAMRON 70-300mm F/4.5-6.3 Di III RXD (Model A047) for full-frame Sony E-mount and Nikon Z mount mirrorless cameras is a telephoto zoom lens designed and created so photographers of all skill levels can enjoy high quality telephoto images comfortably. The 70-300mm F4.5-6.3 covers a broad telephoto zoom range yet is the world’s smallest size and lightest weight[1], coming in at 148mm (5.8″”) long and weighing just 545g (19.2oz)[2]. With special emphasis on resolving power, TAMRON has employed special lens elements appropriately arranged to correct chromatic aberration, generally strong in a telephoto lens, as well as other aberrations. The 70-300mm F4.5-6.3 is a versatile lens for photographing landscapes, sports and other action, pets, wildlife and more. The lens also demonstrates its potential for portrait shooting, casual snapshots and scenarios that require you to be mobile and shoot handheld, like sporting events. The apparent image compression and the close-up effects characteristic of telephoto lenses naturally amplify photographic expression. Zooming in on distant objects and making them appear closer is one of the joys of telephoto shooting.

The lightest and most compact telephoto zoom for mirrorless full format cameras for Sony E-mount and Nikon Z mount
TAMRON presents the 70-300mm F/4.5-6.3, its first telephoto zoom lens for mirrorless full-format cameras with Sony E and Nikon Z mounts. Designed to make telephoto photography effortless for all levels of photographers, it boasts exceptional image quality and holds the title of the world's most compact and lightest lens in its class.
With a length of 148mm (5.8") and weighing just 545g (19.2oz), it offers high-resolution performance and precise correction of optical aberrations. Whether shooting sports, wildlife, portraits, or street scenes, its long focal length provides versatility, enhanced by Sony's advanced camera features like image stabilization and fast autofocus for sharp results in any situation.

A high-resolution telephoto zoom lens that is powerful, portable, and fun
To make the 300mm telephoto focal length more fun and accessible, TAMRON focused intently on designing a telephoto zoom lens that’s both small and lightweight. Turning the conventional concept of a telephoto lens on its head, the 70-300mm F4.5-6.3 is only 148mm (5.8″”) in length with a maximum diameter of 77mm and a weight of just 545g (19.2oz). This gives users the freedom to concentrate fully on shooting without worrying about lens size or weight. In addition to those wishing to pursue real telephoto shooting for the first time, the lens is also recommended for people who use cameras that have built-in image stabilization because they can leave the tripod at home. Of special significance, when paired with the APS-C mirrorless cameras, this zoom adds additional telephoto reach with its 105-450mm equivalent field-of-view, while remaining comfortable to handle.
Achieves the ultimate combination of light weight and outstanding optical performance
The lens is made up of 15 elements in 10 groups with an appropriate arrangement of LD (Low Dispersion) lens elements. Eliminating waste to the extreme degree, TAMRON reduced weight while still achieving very high image quality in the 70-300mm F4.5-6.3. Aberrations such as axial chromatic aberration (which tends to occur in telephoto lens designs) have been well corrected. The 300mm end, which receives particularly frequent use in a telephoto zoom, provides excellent high-resolution performance from the center of the image all the way to the corners. Stunning bokeh is another remarkable feature of this lens. Subjects are accentuated against the beautifully soft bokeh effects in the background. To suppress ghosting and flare, the lens uses BBAR (Broad-Brand Anti-Reflection) Coating, which is renowned for its anti-reflection performance. In addition, the actuation of the lens correction features built into cameras lets users enjoy enhanced performance and functions.


High performance autofocus system means you'll own every shooting opportunity
The AF drive on the 70-300mm F4.5-6.3 includes an RXD motor unit to help you stay focused on the action. RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. A sensor that precisely detects the position of the lens enables high-speed and accurate AF, which is ideal when shooting continually moving subjects or recording video. And with a focusing system that is both smooth and quiet, the 70-300mm F4.5-6.3 lets you shoot free from stress not worrying the drive sound in a quiet environment.
