    Tamron AF 28-300mm lens

    Tamron's 28-300mm zoom lens now features our "Di" design, making it the ideal lens for use with both digital and film cameras. The "Di" design is achieved by applying a new optical design to its coated surfaces, and by further enhancing our already stringent quality control system. Whether you shoot film or digital, the lens provides high image quality for both platforms. When used with APS-C size digital SLR cameras, the lens provides an angle of view equivalent to approximately 44-465mm, covering the standard to ultra telephoto range with no sacrifice of quality or aperture range.

    "Di" (Digitally Integrated design) is the designation Tamron puts on lenses featuring optical systems designed to meet the performance characteristic of digital SLR cameras as well as film cameras. Toward Ever Greater Compactness Featuring Key XR Technology Reducing the total length of the optical configuration, we succeeded in developing optics that allow for a smaller lens diameter while maintaining the same aperture values as previous lenses for overall compactness. Optical power distribution was enhanced in a compact package through the innovative use of XR (Extra Refractive Index) glass, resulting in minimum aberration.

    With a short barrel, it is possible to obtain the same visibility (aperture value) as with a long barrel. By using this principle, we were able to shorten the optic system length for a more compact overall lens design while maintaining aperture values. The ASL lens technology compensates for spherical aberration to achieve outstanding image quality. At the same time, reducing the number of elements results in a more compact, lightweight lens package.
