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. Despite covering a wide range of focal lengths, the lens is lightweight and compact, with a length of 117mm (4.6 in) and a weight of 575g (20.3 oz).
