Tamron 28-200mm F/2.8-5.6 Di III RXD Zoom Lens for Sony E-Mount (Full-Frame / APS-C) — Model AFA071S700, Black

Tamron 28-200mm F/2.8-5.6 Di III RXD designed for Sony E-mount full-frame and APS-C mirrorless cameras — touted as the world’s first F2.8 all-in-one zoom for full-frame mirrorless bodies. Extremely portable, it weighs only 20.3 oz. and measures 4.6" in length. Close-focusing is impressive: 7.5" minimum focus distance at the wide end with a 1:3.1 reproduction ratio, and 31.5" at the tele end with a 1:3.8 ratio. Autofocus is driven by Tamron’s RXD stepping motor unit, which delivers exceptionally quiet operation.
