The Tamron 70-300mm f4.5-6.3 Di III RXD Lens is the lightest compact telephoto zoom available for Sony E‑mount full-frame and APS‑C mirrorless cameras. Weighing just 545 g and measuring 148 mm, it packs industry-leading portability with a maximum reach of 300 mm. Its 15-element / 10-group optical design includes an LD glass element and BBAR coatings to control aberrations and deliver sharp center resolution throughout the zoom range. The RXD stepping motor powers quiet, precise autofocus with full-time manual override, ideal for both video and stills. While it lacks optical stabilization, the lens is moisture-resistant and excels when paired with IBIS-equipped bodies. Close-focus at 0.8 m–1.5 m makes it moderately capable for portraits and travel.
