The Tamron SP 70-200mm F/2.8 Di VC USD G2 (model A025) is a completely new designed professional bright telezoom for full-frame cameras. This new lens was developed by greatly improving all the features of the previous model. These improvements include a thorough review of the optical, mechanical and electronic design to increase autofocus speed and accuracy, enhance Tamron VC (Vibration Compensation) function and shorten minimum focusing distance. All new features include Tamron eBand coating, moisture and dust resistant housing, fluorine coating and compatibility with Tamron 1.4x and 2.0x tele converters. The lens is constructed of metal for better handling and ease of use. The result of this dramatic evolution is the Tamron SP 70-200mm F/2.8 Di VC USD G2, a bright telephoto zoom that enables the application in professional photography with subjects such as portrait, landscapes, sports, fashion and photojournalism.
