The Tamron 17-28mm f2.8 Di III RXD Lens is a compact, fast ultra-wide-angle zoom for Sony E-mount full-frame and APS-C cameras. Weighing just 420 g and measuring 99 × 73 mm, it delivers a constant f/2.8 aperture across its 17–28 mm range, offering excellent low-light capability. Its optical construction includes 13 elements in 11 groups with three aspherical, two LD, and one XLD glass, minimizing distortion and chromatic aberrations. The RXD autofocus motor provides fast, nearly silent focusing and full-time manual override, ideal for both stills and video. Built with moisture-sealed construction and fluorine-coated front, it’s robust and field-ready. With a 0.19 m close-focus and 67 mm filter thread, it excels at landscapes, architecture, astrophotography, and run‑and‑gun video.
