Tamron 70-180mm f/2.8 Di III VXD Lens for Sony E
The 70-180mm F/2.8 features a compact and lightweight design with a 67mm filter diameter, the same as Tamron's highly esteemed 17-28mm F/2.8 (Model A046) and the 28-75mm F/2.8 (Model A036). The optical construction includes several special lens elements that contribute to the lens's overall superb imaging performance. Its very short 33.5" MOD (Minimum Object Distance) expands overall versatility. The lens utilizes Tamron's newly developed VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism that produces an autofocus drive that's quieter and quicker than ever before.
