Tamron 70-300mm F/4.5-6.3 Di III RXD is a versatile telephoto zoom lens made particularly for Sony E-mount full-frame and APS-C mirrorless camera systems. Because it is the world's lightest and smallest 70-300mm full-frame mirrorless mount telephoto zoom, it measures 5.8 inches in length and 19.2 ounces alone, ideal for photographers who seek mobility without compromise in image quality.

This lens features Tamron's RXD (Rapid eXtra-silent stepping Drive) motor, delivering fast, precise, and quiet autofocus—perfect for capturing moving subjects and video shooting. Its optical construction consists of 15 elements in 10 groups, including Low Dispersion (LD) elements to reduce chromatic aberrations, delivering sharp, high-quality images across the zoom range. The BBAR (Broad-Band Anti-Reflection) coating reduces flare and ghosting, enhancing contrast and color accuracy. Additionally, the lens is supported by Sony's in-camera features like Fast Hybrid AF and Eye AF, and also has direct manual focus for greater control.

Ideal for professionals and enthusiasts alike, the lens excels in a variety of photography genres like sports, wildlife, portraits, and landscapes. Its compact size and moisture-resistant construction make it a reliable partner for outdoor photography.
