Tamron 17–28mm f/2.8 Di III RXD (Sony E)
Full-Frame E-Mount • Constant f/2.8 • XLD & LD Elements • BBAR & Fluorine Coatings
Overview
Covering ultra-wide to wide-angle perspectives, the Tamron 17–28mm f/2.8 Di III RXD is a compact, fast zoom for Sony full-frame E-mount. The bright constant f/2.8 aperture improves low-light performance and depth-of-field control, while an optical design with XLD and LD elements delivers high clarity with reduced chromatic aberrations and color fringing. BBAR coatings suppress flare and ghosting for richer contrast in backlit scenes, and a fluorine-coated front element helps resist smudges.
Focusing is driven by an RXD stepping motor for quick, quiet AF that suits both stills and video, with full-time manual override. A close focusing distance of 19 cm (7.5") enables dynamic near-macro perspectives at 0.19× magnification. The lens features a moisture-resistant construction and uses a common 67 mm front filter size to simplify your kit.

Pro Tips
- For astrophotography, shoot wide open at f/2.8 around 17–20 mm and raise ISO as needed; enable long exposure NR for cleaner frames.
- Use a 67 mm circular polarizer or ND for landscapes; the internal zoom keeps balance stable for gimbal work.
- Get dramatic perspectives by focusing close at 19 cm for foreground-rich compositions.
