Tamron has launched a new high-speed zoom lens, introducing the SP 24-70mm F/2.8 Di VC USD G2 (Model A032) for full-frame DSLR cameras which it says can achieve up to five stops of image stabilisation.
Available in Canon and Nikon mounts, the new Tamron 24-70mm f/2.8 boasts newly developed Dual Micro Processing Units that provide rapid autofocusing and help the lens achieve a more precise AF performance, Tamron says.
Meanwhile, its dedicated Vibration Compensation processor – combined with the MPU – employs a new-generation algorithm that enables the lens to provide its five stops of stabilisation, which Tamron says is the highest VC of any lens in its class.
The Tamron 24-70mm f/2.8 lens’s optical construction consists of 17 elements in 12 groups and also employs 2 Extra Refractive Index elements, 3 Low Dispersion elements, 3 Glass-Molded aspherical and one hybrid aspherical lens element which, combined, help reduce chromatic aberrations and distortion.
These interior elements are also what helps Tamron make the lens so compact, the company says.
Tamron’s eBAND (Extended Bandwidth & Angular-Dependency) Coating helps prevent ghosting and flare, while a fluorine coating on the front element surface helps protect it from fingerprints and dirt.
The Tamron 24-70mm f/2.8 release date will be July 2017. Price information was not available at the time of writing.
