The secon version of the Canon EF 24-70mm F2.8 lens is constructed with improved dust sealing and water resistance, while fluorine coatings on the front and rear lens reduce fingerprints and smearing. A circular 9-blade diaphragm gives beautiful, soft backgrounds. A zoom lock lever locks the zoom position at the wide end for safe transporting while attached to an EOS DSLR camera over the shoulder.
Large aperture L-Series standard zoom lens that combines high image quality and enhanced durability. Constant f/2.8 maximum aperture for effective imaging in low light and shallow depth of field.
