At Tamron, our quest has always been to make the ideal zoom lens. As a result of this ongoing challenge, we have introduced the concept of our high-power zoom lens in the new AF18-200mm XR Di II for exclusive use with digital SLRs. Tamron's original development of proprietary core technologies such as Aspherical element production, Multiple Cam Mechanism and Integrated Focus Cam design lend to the creation of the world's lightest, most compact 11.1X zoom lens made for digital SLR cameras.
