Tamron has announced a new high-speed standard zoom for Sony E-mount cameras, introducing the 28-75mm F/2.8 Di III RXD, price tag £699 / $799.
As well as its f/2.8 aperture, the new Tamron lens is constructed of 15 elements in 12 groups, which includes an XLD (eXtra Low Dispersion) element, LD (Low Dispersion) element, GM (Glass Molded Aspherical) element and two hybrid aspherical lens elements for smooth bokeh, Tamron says.
The Tamron 28-75mm F/2.8 Di III RXD also offers a Minimum Object Distance (MOD) of 0.19m (7.5 in) at the wide-angle zoom setting, and at the 75mm telephoto end the 0.39m (15.3 in) MOD provides an image magnification of 1:4.
Other features of the Tamron 28-75mm F/2.8 Di III RXD include a Rapid eXtra-silent stepping Drive (RXD) for quiet autofocus in both video and still capture, and Tamron says the new lens will fully match with various camera-specific features including the in-camera lens correction and Direct Manual Focus (DMF) system features of Sony cameras.
The Tamron 28-75mm F/2.8 Di III RXD boasts a moisture-resistant construction, with fluorine coating to protect against fingerprints and dirt. And it weighs just 550g and measures 4.6 inches.
The Tamron 28-75mm F/2.8 Di III RXD (Model A036）release date will be May 24, 2018.
