Tamron Developing Fast Standard Zoom For Sony


Expanding its lens lineup for mirrorless cameras, Tamron today announced the development of the 28-75mm F/2.8 Di III RXD (Model A036) for Sony full-frame mirrorless cameras. When released, it will be the third lens in the Di III series for mirrorless, joining the 14-150mm F/3.5-5.8 Di III (Model C001) for Micro Four Thirds system cameras, and the 18-200mm F/3.5-6.3 Di III VC (Model B011) available in Canon and Sony mounts.

At the wide end of its range, the 28-75mm F/2.8 Di III RXD will be able to focus as close as 7.5 inches, extending to 15.3 inches at the telephoto end. The lens will feature a fast constant maximum aperture of ƒ/2.8 and a new “RXD” stepping motor AF which Tamron states will be “extremely quiet” and therefore well-suited for video work. It will also be compatible with Sony’s Direct Manual Focus capability, allowing seamless switching between auto and manual focus.

List price and availability date are to be announced. For additional info, see the press release below.

Tamron today also introduced a new telephoto zoom for full-frame DSLRs, the 70-210mm F/4 Di VC USD (Model A034).
