• Tamron AF 28-200MM F/3.8-5.6 XR Di Aspherical [IF] Macro
• Di Lens (will not work on imagers larger than APS-C size)
• MSRP: $490.95
• Availability: Spring 2006

Tamron introduced the 28-200mm zoom lens (Model 71D), the first generation of a new genre of high power zoom lenses for popular use, in 1992. The company's current product, the AF28-200mm Super XR (Model A03), made innovative use of XR (Extra Refractive Index) glass to achieve a remarkably lightweight, compact product that has won wide acclaim among photography fans and solidified Tamron's position as the original pioneer in product development of high power zoom lenses. Now, Tamron has made this lightweight, compact high power zoom lens available with the Di optical system with improved multi-coating for digital SLR cameras as well as film cameras, further enhancing its ease of use and popularity.

MAIN FEATURES

Internal Surface Coating to Reduce Ghosting and Flare

By employing "Internal Surface Coatings" (i.e., multiple-layer coatings on cemented surfaces of plural elements) and new multiple-layer coating technology on ordinary elements, ghosting and flare due to reflections that occur when light enters through the front element and reflections caused by the imagers themselves are reduced to the absolute minimum. Moreover, upgraded advanced quality control was implemented to raise the level of resolution performance standards and prevent flare due to aberrations, which has resulted in a high power zoom lens suitable for photography with digital SLR cameras.

Ease of Use and Compact Size Retained

A 7x magnification power is now available when used with digital SLR cameras. This marks an extension of the intrinsic convenience of digital cameras, which allows photo images to be checked on the spot, and to be processed freely on a personal computer. The lens retains the compact size of the previous model, designed for 35mm film, with all the ease of use of a 28-200mm high power zoom lens. The complete package heightens the pleasure of using digital SLR cameras.

Perfect for Use with Both Digital and 35mm Film Cameras

This lens delivers an ultra-long telephoto zoom range up to a 310mm equivalent on an interchangeable-lens type digital SLR camera, as well as 28mm wide-angle images on a conventional 35mm film SLR camera.

External Design Shared by All Di Lenses

The external design uses a metal relief ring with a special process designation on the ring. The result is heightened visibility and a quality design. Additionally, the black coating over the entire lens barrel creates a high-quality, sophisticated look.
