In January 2020 we had reviewed the Tamron 17-28 mm f/2.8 Di III RXD lens which had received Smart Photography’s Best Buy stamp of confidence. This month we have its senior sibling on test –the Tamron 28-75 mm f/2.8 Di III RXD. This is an E-mount (full-frame) lens designed for Sony interchangeable lens mirrorless cameras. The lens was tested using a Sony A7III body.

Design & Build Quality

Finished in dull black with clear white lettering, the Tamron 28-75 mm lens is sleek and lightweight (555 g with the lens hood, but without both end caps). The outer shell is made from polycarbonate and the build quality is good. The zoom ring, 3 cm wide and textured with a rubberised grip, is toward the filter end. Focal length settings of 28, 35, 50 and 75 mm are clearly marked. Filter size is 67 mm. The lens is designed in Japan but made in Vietnam.

Key Features

The lens (model A036) is constructed with 15 elements in 12 groups that include one XLD (Extra Low Dispersion) element and one LD (Low Dispersion) element to reduce chromatic aberrations and improve colour accuracy; two hybrid aspherical and one molded glass aspherical element to improve sharpness. Further, special BBAR (Broad Band Anti Reflection) coatings are applied to the elements to reduce flare and ghosting and achieve greater contrast. The aperture range is from f/2.8-22 throughout. Autofocus is quick, quiet and smooth, thanks to the RXD (Rapid Extra-silent Stepping Drive).
