The Tamron 70-180mm F/2.8 Di III VXD for full-frame mirrorless Sony E-mount cameras and its light weight and responsiveness make telephoto shooting better than ever. 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 only 67mm, 5.9 in length and a weight of 28.6 oz. And its short 33.5 in MOD broadens the possibilities for photographic expression.
