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. Additionally, the lens is moisture-resistant and has a fluorine coating on the front element to enable its use in trying environmental conditions. Bright f/2.8 constant maximum aperture affords consistent brightness throughout the zoom range and benefits working in difficult lighting conditions. Three glass-molded aspherical elements and one hybrid aspherical element help to reduce chromatic aberrations and distortion throughout the zoom range to deliver notable sharpness and accurate rendering.VC image stabilization helps to minimize the appearance of camera shake by up to 5 stops or more effective handheld shooting in difficult lighting conditions.  An Ultrasonic Silent Drive autofocus motor delivers quick and precise focusing performance to suit working with moving subjects. This motor also affords full-time manual focus control, and it is possible to focus on subjects as close as 1.25' away. The rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
