Characterized by apt focusing speed and image stabilization, the Canon EF-mount SP 24-70mm f/2.8 Di VC USD G2 from Tamron 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. Balancing its optical attributes, this lens also utilizes a USM autofocus motor to deliver notably quick, quiet, and precise focusing performance that suits both stills and video applications. Also, 5-stop-effective Vibration Compensation helps to minimize the appearance of camera shake for sharper handheld shooting in difficult lighting conditions. Additionally, the lens is moisture-resistant EF-Mount Lens/Full-Frame Format Aperture Range: f/2.8 to f/22 Two XR Elements, Three LD Elements Four Aspherical Elements
