Tamron has distilled all the technical capabilities and know-how amassed over the last 28 years in its development of all-in-one zoom lenses into the creation of this 28-200mm F/2.8-5.6 Di III RXD (Model A071), designed exclusively for Sony E-mount. The lens has a large maximum aperture of F2.8 at 28mm wide end, which represents a world’s first for all-in-one zoom lenses, and delivers high-level performance across the entire zoom range, from the 28mm wide-angle end to 200mm telephoto.
