Press Release
July 30, 2008, Saitama City, Japan — Tamron Co., Ltd., under the leadership of Mr. Morio Ono, President, has announced the development of a unique ultra high power zoom lens—the Tamron AF18-270mm F/3.5-6.3 Di II VC LD Aspherical (IF) MACRO (Model B003), the first(1) digital SLR lens in the world that delivers a remarkable zoom ratio of 15X (28-419mm equivalent) and is equipped with a highly effective Vibration Compensation (VC) mechanism. Designed exclusively for digital SLR cameras with APS-C sized image sensors(2) , the new lens delivers outstanding image quality over its entire zoom range and its exclusive VC anti-shake system facilitates sharp handheld photography even at the longest telephoto settings.

With its vast zoom-range, the Tamron AF18-270mm F/3.5-6.3 Di II VC lens enables the user to cover virtually any photographic subject from wide angle to ultra telephoto simply by turning the zoom control. It covers angles of view equivalent to 28mm to 419mm when converted to the 35mm format(3) . In addition, this breakthrough lens is equipped with Tamron’s exclusive, proprietary tri-axial Vibration Compensation (VC) mechanism that eliminates or substantially reduces the effects of handheld camera shake. As a result, the user can enjoy the convenience of handheld photography in virtually any situation, from shooting candid images, to covering sporting events, to news photography, without worrying about camera shake having an adverse effect on image quality. The new lens will be made available in Canon and Nikon mounts. The price and launch date of the new lens will be announced at a later date.
