A great addition to the Sony E-mount, the Tamron 28-75mm f/2.8 Di III RXD strikes a beautiful balance between vibrant image quality, superb bokeh, compact size and lighter weight. Specizlized glass elements throughout control various aberrations and produce stable resolution across the entire zoom range. All the lens surface is treated with Tamron's proprietary BBAR (Broad-Band Anti-Reflection) Coating, which dramatically reduces ghosting and flaring while preserving crisp image quality.
The Tamron 28-75mm f/2.8 Di III RXD is designed to maximize the potential of full-frame mirrorless cameras. It is designed to be your most frequently used high-speed zoom, as it was designed to be as compact as possible. Now you can enjoy advanced optical performance in a compact size with lightweight convenience.The AF drive on the lens includes an RXD (Rapid eXtra-silent stepping Drive) motor unit to help you stay focused on the action. RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. A sensor that accurately detects the position of the lens enables high-speed and precise AF, which is ideal when shooting continually moving subjext or video, With a focusing system that is both smooth and quirt, the Tamron 28-75mm f/2.8 Di III RXD lets you shoot a video without worrying about picking up ambient drive sounds.
