Tamron 28-300mm f/3.5-6.3 XR Di VC LD Aspherical IF Macro Autofocus Lens

The Tamron 28-300mm f/3.5-6.3 XR Di VC LD Aspherical IF Macro Lens is now equipped with a Vibration Compensation (VC) mechanism. This lens is ultra-compact and light-weight, with a constant minimum focus distance of 1.6' (0.5 m) and a high maximum magnification of 1:3. The remarkable achievements are brought about through XR (extra refractive index) glass and efficient use of aspherical lenses. The ideal "all-in-one" zoom lens, for indoor and outdoor use.

The VC mechanism, developed by Tamron, features a triaxial configuration using three pairs of driving coils and slide balls around the compensator group of the lens' optical system. Since the compensator lenses are supported with rolling friction of the balls, the response performance is enhanced and the construction is simple, which results in the compactness of the lens. As a result, dimensional increases are confined to a mere 0.7" (17.8mm) in overall length and about 5mm in diameter.

Di (Digitally Integrated) design is the designation that Tamron uses for lenses that feature the improved optical design that meets the performance characteristics of digital SLR cameras, as well as film cameras. When used with APS-C size (standard) digital Nikon SLR cameras, the lens provides an angle of view equivalent to approximately 42-450mm, covering the standard to ultra telephoto range with no sacrifice of quality or aperture range.
