MAIN FEATURES World's first and greatest zoom ratio of 15X, covering 28-419mm 35mm-equivalent angle of view Going back to the basic concept of "one lens covering everything from wide angle to telephoto," engineers at Tamron took up the difficult task of expanding the zoom range of Tamron's high power zoom lenses even further. Their unstinting efforts to extend the telephoto end beyond previous limits while retaining the wide-angle end at 18mm has borne fruit as an ultra high power zoom lens that is exclusively designed for DSLR cameras and boasts the greatest zoom range of 15X for the first time in the world. Tamron's original VC mechanism for effective shake-free hand-held photography Tamron's proprietary VC (Vibration Compensation) mechanism was built in the AF28-300mm F/3.5-6.3 Di VC (Model A20) for the first time. It demonstrated its powerful compensation effect employing a tri-axial system that is designed to let three coils drive a compensator lens electromagnetically via three steel balls. Since the compensator lens is supported on rolling steel balls with very low friction, follow-up performance is also enhanced, resulting in stabilized viewfinder images. Since the mechanism is designed to allow parallel shifting of the compensator lens solely by means of electrical control, the mechanical construction is simpler and more compact, so the lens can be kept as small and light as possible.
