Release Issued by Tamron:

Tamron AF18-250mm F/3.5-6.3 Di-II LD Aspherical (IF) Macro

September 2006 Photokina in Cologne, Germany:Tamron announces the new AF18-250mm F/3.5-6.3 Di-II LD Aspherical (IF) Macro (Model A18), a lightweight, compact and ultra high power zoom lens designed exclusively for digital SLR cameras with APS-C sized imager sensors.

This new AF18-250mm F/3.5-6.3 Di-II LD Aspherical (IF) Macro is the ultimate high power zoom lens boasting the world’s greatest zoom ratio(*1) of 13.9X, a milestone that Tamron, the pioneer of high power zoom lenses, has achieved by commanding its technologies to further expand the capabilities of high power zoom lenses.

（*1) As of September 2006. Based upon Tamron’s research of lenses for exclusive use
with digital SLRs equipped with APS-C sized image sensors.

The new zoom lens covers up to a 250mm telephoto focal length, the longest focal length among zoom lenses that start with an 18mm wideangle focal length available on the market for exclusive use with digital SLR cameras. Thus, it provides an impressive telephoto effect that is entirely different from the effect obtainable at 200mm on conventional high power zoom lenses. The new zoom lens will satisfy the expectations of photographers that are used to the 300mm tele-end of Tamron’s AF28-300mm Di (Model A061) when used on a digital SLR camera.

Di (Digitally integrated)-II lenses are designed for exclusive use with digital SLR cameras having APS-C size imagers. Di-II lenses are not designed for use with 35mm film cameras nor digital SLR cameras with image sensors larger than 24 x 16mm. The ratio Tamron uses to convert 35mm focal length equivalents is 1.55X.
