Compact Full-Frame Telephoto Zoom – 70-300mm Dynamic Focal Range (105-450mm APS-C Equivalent), Ultra-Lightweight 1.2 lb Form Factor Measuring Just 5.8″ Long, RXD (Rapid eXtra-silent stepping Drive) Autofocus Motor, Full Support for Sony Fast Hybrid AF and Real-Time Eye AF, One Low Dispersion (LD) Element, Rounded 7-Blade Diaphragm, Moisture-Resistant Construction with Aluminum-Magnesium Alloy Barrel Elements, Front and Rear Caps with Dedicated Lens Hood Included, Native Full-Frame Sony E-Mount (Excellent Condition)
The Tamron 70-300mm f/4.5-6.3 Di III RXD is a compact, high-mobility telephoto zoom lens engineered specifically for full-frame Sony E-mount mirrorless cameras (and fully compatible with APS-C bodies, where it yields an extended 105-450mm equivalent reach). Spanning a versatile short- to long-telephoto focal spectrum, this lens delivers powerful subject magnification while maintaining an exceptionally portable profile—measuring a mere 5.8 inches in length and weighing just 1.2 pounds. Designed to eliminate the cumbersome bulk traditionally associated with telephoto zooms, it serves as an ideal handheld optic for wildlife tracking, outdoor sports, action photojournalism, compressed landscapes, and travel portraiture.
The optical formula comprises 15 elements arranged in 10 groups, incorporating one precisely positioned Low Dispersion (LD) element to suppress axial chromatic aberrations, color fringing, and distortions that often affect telephoto designs. The lens fully integrates with Sony camera bodies to support in-camera lens corrections, including peripheral shading, chromatic aberration, and geometric distortion compensation. Autofocus is powered by Tamron’s RXD (Rapid eXtra-silent stepping Drive) linear motor unit, delivering high-speed, pin-point precision, and virtually silent focus transitions suitable for both rapid continuous burst photography and smooth video tracking. Fully optimized for Sony’s imaging ecosystem, it natively supports Fast Hybrid AF, Real-Time Eye AF, and Direct Manual Focus (DMF). Built with moisture-resistant seals and a durable aluminum-magnesium alloy framework, the lens provides dependable outdoor reliability, while firmware can be seamlessly updated via the camera body using the dedicated TAMRON Lens Utility platform.
