Tamron Autofocus 18-200mm f/3.5-6.3 XR Di II Macro Lens for Nikon Digital SLR Cameras

The Tamron AF18-200mm high power zoom lens features an entirely new optical design using XR (Extra Refractive Index) glass in an innovative way in order to optimize the overall distribution of optical power throughout the entire zoom range. This design reduces various aberrations to the absolute minimum and achieves remarkable downsizing at the same time. In addition, three hybrid aspherical lens elements and two LD (Low Dispersion) glass elements are used to accomplish effective compensation of on-axis and lateral chromatic aberrations, a critical factor to enhance the optical quality in digital photography. As a result, the lens provides outstanding optical quality in a multi-purpose zoom lens. A glare-reducing flower-shaped lens hood is included as a standard accessory. The special hood provides optimum shading of superfluous light rays that enter from the rectangular frame outside the 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. 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 ...Read more

************************************

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
