Characterized by apt focusing speed and image stabilization, the Tamron 24-70mm f/2.8 Di VC USD G2 is a revised fast standard zoom covering a versatile wide-angle to portrait-length range. A sophisticated optical design with two extra refractive elements, three low dispersion elements, three glass-molded aspherical elements, and one hybrid aspherical element helps to suppress aberrations and distortion throughout the zoom range while eBAND and BBAR coatings have been applied to individual elements to control lens flare and ghosting for improved contrast and color fidelity.
