Tamron has introduced the 28-200mm F2.8-5.6 Di III RXD zoom lens for full-frame Sony mirrorless bodies. This compact lens is just 11.7cm (4.6″) long and weighs in at 576g (20.3oz).
It features a total of 18 elements, including glass-molded aspherical, hybrid aspherical, extra low-dispersion (known as XLD) and low-dispersion elements. A ‘BBAR’ coating reduces flare and ghosting. The minimum focus distance is just 19.1cm (7.5″) at wide-angle and 80cm (31.5″) at telephoto.
