This zoom lens delivers superior optical performance, with both excellent image quality and beautiful background blur (bokeh). This is only possible thanks to high brightness, rounded aperture blades and a new optical system specially designed for Sony mirrorless cameras. In addition to taking portraits with a creative, blurred background, photographers can enjoy dynamic wide-angle perspectives like never before, thanks to a unique minimum focusing distance of just 0.19m in wide-angle mode. The usability and versatility inherent in compact full-frame mirrorless cameras is enhanced by the compact length and low weight of the Tamron 28-75mm, which is only 117.8mm and 550 gram. The Tamron 28-75mm Di III RXD features an entirely new Tamron-designed fast and accurate AF system. The RXD (Rapid eXtra-silent stepping Drive) delivers the perfect balance between speed and quiet operation, making it perfect for both video and photo shooting. The housing has a moisture-resistant construction that is essential for shooting in adverse conditions, plus a hydrophobic fluorine coating that is highly resistant to moisture, fingerprints and dirt. Finally, the Tamron 28-75mm Di III RXD fully matches the various Sony camera-specific features, such as in-camera lens correction and Direct Manual Focus (DMF). As a result, this new professional zoom fully benefits from the advanced camera functions, which provide a comfortable user experience.
