The Canon EF 24-70mm f/2.8L USM Zoom Lens is a large-aperture L-Series zoom lens that combines high image quality with enhanced durability. The lens combines two types of aspherical lenses to help reduce spherical aberration over the entire image area and through the full zoom range to produce images with high resolution and contrast. Optimized lens coatings help ensure exceptional color balance while minimizing ghosting.
A ring-type USM and high-speed CPU with optimized AF algorithms ensure silent, fast autofocusing. A circular 9-blade diaphragm gives beautiful, soft backgrounds.
