The Tamron AF 18-200mm f/3.5-6.3 XR Di-II LD Aspherical (IF) Macro Lens
made for the Nikon SLR system incorporates a motor built into the lens
itself, which gives it the capability to autofocus with all Nikon DSLR
cameras (including the D40 and D40x). In addition, with the motor built
into the lens, focusing will be quieter and more responsive.
The 18-200mm f/3.5-6.3 XR Di-II is a high power zoom lens designed exclusively for digital SLR cameras using the more compact (APS-C) digital size image sensors. The focal length of this lens is equivalent to approx. 28-300mm in 35mm format.
Designed as an "all-in-one" lens, it will meet almost all photographic opportunities without changing lenses.
The 18-200mm zoom lens realizes an MFD (Minimum Focus Distance)
of 1.5' (45 cm) over the entire zoom range by the employment of a new
optical/mechanical design configuration. Since the maximum magnification
ratio at f=200mm is 1:3.7, you can enjoy close-up photography easily
Note! Di-II lenses cannot be used
with digital SLR cameras using image sensors that are larger than that
of an APS-C size imager, or with 35mm film SLR cameras.
Product Overview Di II: Lenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of our Di products. These lenses are not designed for 35mm film cameras and digital cameras with image sensors larger than 24mm x 16mm. At Tamron, the quest has always been to make the ideal zoom lens. As a result of this ongoing challenge, they 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.
