Tamron 28-75mm F/2.8 Di III RXD lens for Sony FE

In February, Tamron announced development of a 28-75mm F2.8 Di III RXD lens for Sony full-frame mirrorless cameras. Tamron officially launched the lens this morning, revealing full specs, release date, and pricing information for the first third-party standard zoom to be created natively for the Sony FE mount. Here’s a video introduction to the new zoom lens:

The lens was designed from the ground up for Sony full-frame mirrorless cameras, and engineers at Tamron focused on three main features: optical quality, portability, and silent autofocus. The lens weighs in at just 19.4oz (550g) and measures just 4.6in (11.6cm) long. And while the body was made of polycarbonate instead of metal (to save weight) the lens is still ‘moisture resistant’ so you can use it in inclement weather.

Optically, the lens is made up of 15 elements in 12 groups, including an XLD (eXtra Low Dispersion) element, a LD (Low Dispersion) element, a GM (Glass Molded Aspherical) element, and two hybrid aspherical elements that have been arranged “in the optimal arrangement to correct aberrations and reduce the overall lens size,” according to Tamron.

Finally, as the name suggests, the lens features Tamron’s new RXD (Rapid eXtra-silent stepping Drive) autofocus motor. This new stepping motor offers quick, precise, and “exceedingly quiet” autofocus that Tamron claims “virtually eliminat[es] extraneous AF drive sounds during video recording.”
