The optical design includes several specialized glass elements that contribute to the lens's superb imaging performance. The lens's very short 0.85m (33.5 in) MOD (Minimum Object Distance) expands overall versatility. The lens adopts Tamron's newly developed VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism that produces a quiet, quick autofocus drive.
Other features that support a great shooting experience include a Moisture-Resistant Construction helpful for outdoor shooting and Fluorine Coating for easy maintenance. In addition, the Model A056 is fully compatible with various camera-specific features including Fast Hybrid AF and Eye AF.
