The Tamron 70-180mm F/2.8 Di III VXD (Model A056) is a large-aperture telephoto zoom lens for Sony E-mount full-frame mirrorless cameras. The greatest feature is its outstanding performance even while attaining a fast F/2.8 aperture across the entire zoom range and offering the world’s lightest and most compact package with a filter diameter of 67mm, maximum diameter of 81mm, 149mm (5.9 in) length (at the 70mm setting) and a weight of 810g (28.6 oz). Thanks to the generous use of special lens elements, the 70-180mm F/2.8 achieves excellent image quality, and with the short MOD (Minimum Object Distance) of 0.85m (33.5 in), it also broadens the possibilities for photographic expression. For enhanced AF drive efficiency, Tamron has newly developed the VXD (Voice-coil eXtreme-torque Drive), a linear motor focus mechanism that delivers excellent quietness and agile performance, thereby producing the highest level of autofocusing speed and precision in Tamron’s history. Additionally, a floating system is used to achieve excellent optical performance at all shooting distances. By simultaneously operating two VXD units via electronic control, the system produces clear and sharp images of all objects near and far. Moisture-Resistant Construction and Fluorine Coating are employed to facilitate outdoor shooting, and the lens is fully compatible with camera-specific features like Fast Hybrid AF. This remarkable 70-180mm F/2.8 is the third member of Tamron’s exciting trio of fast F/2.8 zoom lenses for full-frame mirrorless cameras.
