Telephoto zoom takes you closer to the action

The world's smallest and lightest* telephoto zoom lens for Sony full-frame E-mount mirrorless cameras

* Among 300mm-capable telephoto zoom lenses for full-frame mirrorless cameras (As of August, 2020: Tamron)

The 70-300mm F/4.5-6.3 Di III RXD (Model A047) for Sony full-frame E-mount mirrorless cameras is a telephoto zoom lens designed and created so photographers of all skill levels can enjoy high quality images comfortably. It achieves the world's smallest size and lightest weight, coming in at 148mm (5.8 in) long with a maximum diameter of 77mm, and weighing just 545g (19.2 oz).

With special emphasis on resolving power, Tamron has deployed special lens elements appropriately arranged to correct chromatic aberration, generally very strong in a telephoto lens, as well as other aberrations. Users can enjoy high-resolution images combined with the stunning bokeh qualities that are achievable only with a telephoto lens.

The lens also incorporates the RXD (Rapid eXtra-silent stepping Drive) stepping motor unit, a high-speed precision AF drive system that is remarkably quiet.

The 70-300mm F4.5-6.3 is a versatile lens for photographing landscapes, sports and other action, pets and wildlife and more.

High quality images with beautiful, dreamy bokeh

The lens is made up of 15 elements in 10 groups with an appropriate arrangement of LD (Low Dispersion) lens elements. 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 (intentional background blur qualities) are another remarkable feature of this new lens.

Superb AF keeps it sharp and quiet

The AF drive incorporates an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit. RXD uses an actuator that is able to precisely control the rotational angle of the motor, allowing it to drive the focusing lens without passing through a reduction gear.

The addition of a sensor that detects the position of the lens to a high degree of accuracy enables high-speed and precise AF, which allows you to maintain razor-sharp focus when shooting continually moving subjects or filming video. The lens is also remarkably quiet, eliminating concerns of drive sounds being picked up while shooting video.

Built with Mirrorless in Mind

Tamron’s new 70-300mm F4.5-6.3 zoom is compatible with many of the advanced features that are specific to mirrorless cameras. This includes:

• Fast Hybrid AF- Eye AF
• Direct Manual Focus (DMF)
• In-camera lens correction (shading, chromatic aberration, distortion)
• Camera-based lens unit firmware updates

Additional features:

• Moisture-Resistant Construction
