On April 24, 2014, Tamron has announced the release of the SP 150-600mm f/5-6.3 Di VC USD (Model A011), a 4x ultra-telephoto zoom lens for Nikon mount. This lens has been awarded the TIPA (Technical Image Press Association ) Award for Best Expert D-SLR Lens in 2014. The Nikon mount model will be first launched in the Japanese market, with overseas launches to follow in mid-May. The launch date of the Sony mount model will be announced at a later date. Mounted on APS-C DSLR cameras, it has an equivalent focal length range of 233mm to 930mm. The lens has 20 elements in 13 groups, with three LD (Low Dispersion) glass elements for enhanced optical correction, enabling the lens to compensate for on-axis aberrations at thefg telephoto end. The lens also adopts eBAND (Extended Bandwidth and Angular- Dependency) Coating and conventional BBAR(Broad- Band Anti-Reflection) Coating to reduce ghosting and flare. It has a 9 blade circular diaphragm for bokeh effect and offers Vibration Compensation. The lens also features a redesigned tripod mount and comes with SILKYPIX Developer Studio, a RAW image development processing software for Tamron’s SP lenses.
