Super-compact design
Tamron has adopted a dedicated design for mirrorless cameras and achieved a compact size once again by fixing the aperture at F/6.3 at the telephoto end. The maximum diameter is 77mm. Measuring just 148mm and weighing a mere 545g, this 70-300mm F/4.5-6.3 Di III RXD is the world’s smallest and lightest telephoto zoom lens for full-frame mirrorless cameras. Compatible with Sony’s popular E-mount cameras, it has been developed with the concept ofenabling photographers to more easily experience the universe of full-scale, full-frame 300mm telephoto photography.

Fast and quiet AF
The AF drive system incorporates the exceptionally quiet RXD (Rapid eXtra-silent stepping Drive) stepping motor. This achieves very fast and accurate autofocus operation and allows users to maintain tack-sharp focus on continuously moving subjects shot at the telephoto zoom position. Because this lens is compatible with Sony camera features, including in body image stabilization and Eye AF, you can enjoy comfortable, high-speed, high precision telephoto photography, even handheld.

Superb optical performance
The optical design includes 15 elements in 10 groups, with an LD (Low Dispersion) lens element precisely arranged to suppress axial chromatic and other aberrations. At 300mm the lens delivers excellent resolution from edge-to-edge. Overall, the efficient optical construction (which also contributes to its light weight) plus Tamron’s BBAR (Broad-Band Anti-Reflection) Coating combine to capture extremely clear, crisp imagesacross the entire zoom range.
