70-300mm F/4.5-6.3 Di III RXD

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) in length with a maximum diameter of 77mm and a weight of just 545g (19.2 oz). 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 and while remaining comfortable to handle. Users can enjoy shooting with even higher power telephoto effects at a maximum equivalent focal length of approximately 450mm³.

The 70-300mm F4.5-6.3 zoom's optical design was refined via thorough simulations utilizing the latest technologies. 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 are another remarkable feature of this new 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.

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.

With the Nikon Z mount version, users can employ the dedicated TAMRON Lens Utility software that was developed in-house by TAMRON⁴. This application enables users to easily update the lens to the latest firmware themselves without going through the camera⁵.

4 To connect your PC and lens, use the TAMRON Connection Cable (USB Type-A to Type-C/ Model CC-150, or USB Type-C to Type-C/ Model CC-350) sold separately.
5 As the 70-300mm F4.5-6.3 is not equipped with a Focus Set Button, certain functions cannot be customized.

Great things come in compact packages! This lineup includes other lenses that share the same filter diameter of 67mm. Lenses in this series feature small and light designs suitable for pairing with mirrorless cameras, and the filter diameter of each lens is the same 67mm. In addition to providing excellent portability when carrying multiple lenses, costly Polarizers, ND and other filters can be used interchangeably. Plus, the hassle of looking for different-sized lens caps when switching lenses has been eliminated. In addition to outstanding optical quality, you will enjoy the highest level of convenience across the entire lineup.
