Tamron announces 17-70mm F2.8 lens for Sony APS-C

Tamron has announced a new lens for Sony APS-C bodies, the 17-70mm F2.8 Di III-A VC RXD.

The lens is described by Tamron as the world’s first high-speed standard zoom lens for APS-C cameras with the focal length range of 17-70mm 4.1x zoom ratio (just in case you were wondering!)

The new glass is equivalent to 25.5-105mm in 35mm format and has a total of 16 elements inside, including one hybrid aspherical and two glass-molded aspherical elements. The focus is driven by Tamron's silent stepping drive motor. 

The 17-70mm F2.8 also features Tamron's proprietary vibration control mechanism. Algorithms along with a dedicated, independently operating MPU all combine to compensate for vibration, and the feature is available when the lens is used with cameras with or without in-body image stabilisation.

The lens has a minimum focus distance of 19cm, and a maximum magnification of 0.21x. It's 12cm long and weighs 524g. There's weather-sealing built-in as well.

The 17-70mm F2.8 Di III-A VC RXD will be available from usual retailers in mid-January for $1,399.00 AUD.
