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.

(1) “The world’s longest zoom range” and “world’s first” are statements that apply to interchangeable lens exclusively designed for digital SLR cameras equipped with APS-C sized image sensors, as of June 2008, according to Tamron’s survey.
(2) Di (Digitally integrated) II lenses employ optical systems designed for exclusive use on digital SLR cameras equipped with smaller sized (APS-C sized) image sensors. Di II lenses are not designed for use with 35mm film cameras or digital SLR cameras with image sensors larger than 24mm x 16mm. (This special note “APS-C sized image sensors” is hereinafter omitted.)
(3) Tamron’s conversion value is 1.55X

    Thanks to the vibration compensation and 15x zoom range, this must be the most versatile dslr lens ever. is Tamron pushing too far, well I am not sure. Same thing was told for the 18-250mm too. Here is a nice spec comparison of Tamron 18-270mm VC and Tamron 18-250mm:

    I just got the lens and it seems as if I am having to struggle with turning the lens from close to far – also the vibration reduction inhibits me from getting shots – i’m not sure if it might be the AF

    we’ll see – i’m still experimenting
