The lens is the successor to the AF 18-200 mm f/3.5-6.3 XR Di II LD Aspherical [IF] Macro, which has been one of Tamron’s best-selling lenses since its introduction 10 years ago.
The company says the new lens uses the most modern optical and mechanical design to achieve compactness and high performance.
The lens is the equivalent of 28-310 mm and will focus as close as 0.5 m / 19.7 in.
By incorporating a newly designed autofocus drive module with DC motor-gear train integration, the 18-200 VC also focuses much more quickly and quietly than models with conventional DC motors.
The lens has 16 elements in 14 groups, using an LD (Low Dispersion) lens element to minimize chromatic aberrations and features moisture-resistant construction. The lens also comes with a Zoom Lock feature to prevent unwanted barrel extension when users carry their lens and camera body combinations with the lens pointed toward the ground.
Filter size is 62 mm.
The lens is scheduled to be available later this month, initially for Canon and Nikon mounts, with Sony mount to follow later.
