Long name, short lens. Tamron’s AF 18-270 mm f/3.5-6.3 Di-II VC PZD lens for APS-C sensor-size DSLRs boasts the world’s highest zoom range at 15x magnification for a lens with its compact size and light weight, with VC (Vibration Compensation) image stabilization. At 450 g, measuring 88 mm in length (from mount face to the tip of the lens), and 74.4 mm in diameter with a filter diameter of 62 mm, it is a compact and easy-to-carry lens.
The autofocus unit is driven by Tamron’s new PZD (Piezo Drive), an ultrasonic motor that delivers faster and quieter focusing. Due to its small size, the Piezo Drive motor allows for more compact lens size.
Minimum focus distance is 0.49 m (19.3 in).
Compatible mounts: Canon, Nikon, Sony (although this mount does not include the VC image stabilization functionality as the body of Sony DSLRs contains built-in image stabilization).
Delivery is expected January 2011 for the Canon and Nikon mounts, with a Sony-compatible mount at a later date. Pricing is yet to be announced.
