Tamron Autofocus 18-200mm f/3.5-6.3 XR Di II Macro Lens for Nikon Digital SLR Cameras Since the lens is designed exclusively for digital SLR photography, it provides high image quality in terms of resolution, contrast and flatness of image field It employs a new optical system designed to confine the changing angles of incidences of light rays reaching the imager within a certain scope over the entire image field from the center to the periphery, by considering the effects of variances due to zooming Peripheral light fall-off is minimized when compared with that of conventional lenses for film cameras so that images are uniformly bright from the center to the periphery Complicated mechanisms are built in the compact body thanks to new mechanical artifices. The lens is a multi-purpose zoom lens, yet excellent portability and ease of use are assured. A number of invisible engineering innovations required to downsize the lens, produce high precision parts and increase durability are incorporated in the new AF18-200mm F/3.5-6.3 XR Di-II LD Aspherical (IF) MACRO Compatible w/ the following D-SLR cameras: Nikon D50, D70s, D80, D200, D2Xs, D2Hs & earlier models plus the Fuji S5 Pro & earlier models
