TAMRON ANNOUNCES DEVELOPMENT OF F/2.8 FAST ULTRA-WIDEANGLE ZOOM LENS WITH VC[1] (VIBRATION COMPENSATION), WORLD'S FIRST[2] IN ITS CATEGORY - SP 15-30MM F/2.8 DI VC USD（MODEL A012)

XGM (eXpanded Glass Molded Aspherical) element and LD (Low Dispersion) glass elements deployed in the front group ensures outstanding image depicting performance. Proprietary eBAND coating coupled with improved BBAR coating efficiently reduces ghosting and flare inherent to wideangle focal lengths to an absolute minimum.

Tamron Co., Ltd. (President & CEO: Morio Ono), a leading manufacturer of precision optics, announces development of a new ultra-wideangle zoom lens for full-frame DSLR cameras with a fast F/2.8 aperture and VC (Vibration Compensation), the world's first in its category. The price and launch date are to be determined. 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).

Since 2012, Tamron has been expanding its lineup of interchangeable lenses for 35mm full-frame DSLR cameras. SP 24-70mm F/2.8 was the first in the series, being integrated with VC, followed by the 70-200mm F/2.8, 90mm F/2.8 Macro, and 150-600mm F/5-6.3. 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.

Superb image quality and performance

With an optical construction of 18 elements in 13 groups, inclusive of XGM (eXpanded Glass Molded Aspherical) element placed at the front group and several LD (Low Dispersion) glass elements in the system, aberrations such as geometrical distortion and lateral color are efficiently compensated for enabling the zoom lens to deliver outstanding image quality throughout the entire range from corner to corner.

Prominent competence of VC when shooting night scenes and under low light conditions

Recognizing the needs for image stabilization capability on a wideangle lens voiced by a number of photographers, especially for a full-frame, fast F/2.8 ultra-wide-angle zoom lens category, VC is tuned for providing discernible competence throughout the entire zoom range. The feature enhances image depicting capabilities for shooting night scenes and under low light conditions.

Benefit of the eBAND and the improved BBAR coatings

Tamron's acclaimed BBAR (Broad-Band Anti-Reflection) coating is further refined to render uniformity in transmissivity across the critical bandwidths. Coupled with the eBAND coating, ghosting and flare typically observed on ultra-wideangle lenses are efficiently eliminated, resulting in crisper and crystal-clear images.

Fluorine coating on the front element, Tamron's first

Due to the large diameter and the prominent convex profile of the front element, it is not practical to deploy a protective filter. For the first time, a fluorine coating is applied to the front element, which repels water or any type of dirt, while making it easier to remove such smudge when contaminated.

Fascinating background "bokeh" with the fast maximum aperture of F/2.8

Natural and smooth blur on the subject background enhances depictive capabilities of wide-angle photography when a subject is located in the close distance. The 9-blade diaphragm construction retains a near-circular aperture opening even when stopped down by two steps from its full open position and delivers ideal bokeh effects.

Easy-to-use autofocus

Speed of autofocus and control accuracy are further improved.

USD[4] (Ultrasonic Silent Drive) delivers tack-sharp images due to the high torque and fast response speed with least amount of lag time, yet with extremely low acoustic noise. Equipped with a full-time manual focus mechanism, fine focus adjustments are enabled without exiting from the AF mode.
