Tamron 18-200mm F/3.5-6.3 DI III VC For Sony's NEX-Series Cameras
Tamron has created a high-power all-in-one zoom lens that is compact and lightweight, featuring a 62mm filter and weighing only 16.2 oz., while at the same time delivering superlative image quality. This compact size lets users easily shoot across an extended range - from wide-angle to full telephoto - with just one lens. Converted to the coverage of the 35mm format, this is equivalent to a range of 27mm wide-angle up to 300mm full telephoto.
Equipped with Tamron's VC (Vibration Compensation), and thanks to its light weight and compact size, this lens allows easy handheld shooting of sharp images with no camera shake over a wide range of settings, from everyday snapshots to memorable travel scenes. The AF drive has a stepping motor that is optimal for the Contrast-detection AF system employed by NEX series cameras. This also gives the drive a quieter operation, which is ideal for shooting video in which voices are recorded. In addition, ease of operation is enhanced with the Direct Manual Focus (DMF) function, which allows the user to make fine manual adjustments after initially focusing by AF.
The lens's autofocus mechanism uses a stepping motor that is an ideal match for the Contrast-detection AF system used in Sony's NEX series cameras. The stepping motor's actuator allows finely tuned control of angular rotation, and since it drives the focusing mechanism directly without an intermediate reduction gear, it also provides superbly quiet performance.
