The compact, lightweight and relatively inexpensive Tamron 70-180mm f/2.8 DI III VXD Lens complements the popular f / 2.8 line of zoom lenses for Sony mirrorless cameras with E mount (35 mm).

Compact and lightweight zoom with a length of 149 mm and a weight of 815 g. The filter diameter is 67 mm, like all other Tamron lenses for full-frame mirrorless cameras with Sony E mount. Superb optical performance and MOD 0.85 m widening creative possibilities. Unusually quiet and fast new autofocus drive based on the VXD linear motor. Moisture-resistant design and fluoride coating of the front lens, contributing to effective and comfortable shooting. Compatible with various in-camera functions, including Fast Hybrid AF and Eye AF.
