Tamron is working on a 28-75mm F2.8 lens for full-frame Sony mirrorless cameras. This is the Tamron’s first ever lens for the Sony full-frame E-mount system.
The new high-speed standard zoom lens, 28-75mm F/2.8 Di III RXD will offer a minimum focus distance of 19cm/7.5in at wide-angle, will measure 11.7cm/4.6in long and weigh in at 19.4oz/1.2lb. Tamron claims the lens will offer excellent optical performance and high-quality bokeh. An ‘RXD’ stepping motor autofocus unit provides quiet operation for video applications, and the whole thing will be moisture-resistant.
The lens incorporates an all-new high-speed and precise AF driving system called RXD(Rapid eXtra-silent stepping Drive) which operates with remarkable quietness, making it perfect for video use. It’s also compatible with the “Direct Manual Focus (DMF)” feature that enables Sony cameras to instantly switch between autofocus and manual focus.
