Tamron\'s new high-power zoom lens is a photographer\'s dream come true — it is the result of Tamron\'s continuing mission to develop the world\'s most unique \"one-lens-does-it-all\" zooms to satisfy our customers\' desire. While conventional 35mm film cameras required two lenses to cover 28-388mm, Tamron\'s new zoom is 13.9X, the world\'s most powerful zoom delivering enormous photographic freedom in a single compact lens. The life of a digital photographer has never been better.
