The AF28-300mm F/3.5-6.3 XR Di VC covers everything from wide-angle to telephoto and macro. Tamron has incorporated a Vibration Compensator an anti-shake mechanism developed by Tamron into this highly versatile zoom lens.
The new AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) MACRO zoom lens offers the convenience, comfort and versatility of a high power zoom lens and the capability to reduce hand-shake blur on DSLR cameras using either APS-C size or full-size format imagers.
When the AF28-300mm F/3.5-6.3 XR Di VC is used with a full-size format SLR camera, it covers a tremendous focal length range from 28mm in wide angle to 300mm ultra telephoto. When mounted on a DSLR with an APS-C sized imager, the lens covers a 43mm wide angle to 465mm ultra telephoto(*) (full size format equivalent, in a diagonal angle of view of 5ï¿½20').
The proprietary VC (Vibration Compensation) 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. The lens incorporates a highly accurate gyro sensor for detecting hand-shake, which, combined with a 32-bitRISC CPU, offers comfortable anti-vibration effects.
Outstanding Design Realizing High Zoom Power, VC Mechanism and Compactness
The AF28-300mm F/3.5-6.5 XR Di VC integrates optical technologies that Tamron has accumulated as the pioneer and leader of high power zoom lenses in order to realize the desired compactness even while incorporating the VC mechanism. The optical system uses a number of lens elements made from special optical glass materials including XR (high refraction index) glass elements, GM (glass-molded) elements, hybrid aspherical elements, LD (low dispersion) glass elements to compensate for on-axis and lateral chromatic aberrations and AD (anomalous dispersion) glass element. The lens offers high contrast, high resolution performance and flatness of the image field as a one-does-it-all zoom lens designed to match the characteristics of DSLR cameras.
Revolutionary MFD of 19.3" (0.49m) Throughout Zoom Range Provides 1:3 Macro Magnification Ratio
The AF28-300mm F/3.5-6.3 XR Di VC MACRO boasts an MFD (minimum focusing distance) of 19.3" (0.49m) over the entire zoom range, a top-class close focusing capability among high power zoom lenses for full-size format SLR cameras, which provides the remarkable maximum macro magnification ratio of 1:3 at the 300mm telephoto end.
