The AF in the patent is driven by 2 motors, the main STM and an auxiliary DCM motor. This should be useful especially for continuous shooting & focusing in the videographers domain.

Since 2012, Tamron has been expanding its lineup of interchangeable lenses for 35mm full-frame D-SLR cameras. SP 24-70mm F/2.8 Di VC USD (Model A007) was the first in the series, being integrated with VC, followed by the SP 70-200mm F/2.8 Di VC USD (Model A009), SP 90mm F/2.8 Di MACRO 1:1 VC USD (Model F004), and SP 150-600mm F/5-6.3 Di VC USD (Model A011). The array of those new lenses have been highly acclaimed among the photo enthusiasts and working pros around the globe. To address the needs for more towards the wider angular field, Tamron spearheaded the development of SP 15-30mm F/2.8 Di VC USD, a fast ultra-wideangle zoom lens with the image stabilization feature, setting itself apart from the rest of zooms in this category.

The lens will be showcased at the Tamron booth at Photokina 2014, September 16- 21, 2014 in Cologne, Germany. (Photokina Booth Number: Hall 4.2 D10 – E19).
