The Canon EW-83F is the genuine Canon-designed petal-style lens hood for the EF 24-70mm f/2.8L USM (original, non-IS version). Engineered to block stray light from striking the front element, it reduces lens flare and ghosting while helping to maintain contrast and image quality in challenging lighting conditions. The hood attaches securely to the lens via a bayonet mount and features a matte, non-glare interior finish that further suppresses unwanted reflections inside the hood itself. When not in use, it reverses neatly onto the lens barrel for compact, travel-friendly storage. The petal shape is precisely optimised for the 24-70mm zoom range, maximising coverage without intruding into the frame, and the extended profile also provides a useful degree of physical protection for the front element against knocks, moisture, and dust.
