As a leading camera lens manufacturer 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 the Tamron 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). Aside from day-to-day portability the 28-200mm F2.8-5.6's lightweight and compact size make it especially convenient for travel photos where users wish to avoid the burden of heavy baggage. Tamron has also taken an uncompromising approach to optical performance making liberal use of special lens elements-including LD (Low Dispersion) and XLD (eXtra Low Dispersion)- to greatly suppress chromatic aberrations and making it possible to achieve high image quality from edge to edge. With an MOD (Minimum Object Distance) of 0.19m (7.5 in) at the wide end and 0.8m (31.5 in) at the telephoto end the lens also offers high-level close-up shooting performance. The AF drive system is powered by the RXD (Rapid eXtra-silent stepping Drive) stepping motor unit to deliver high-speed high-precision performance. The lens also features Moisture-Resistant Construction and Fluorine Coating for added protection. When it comes to all-in-one zooms the innovative 28-200mm F2.8-5.6 is in a class by itself and vividly captures virtually all possible scenes from landscape photography to portrait photos and snapshots.
