Dedicated to the Canon RF 35mm f/1.8 IS Macro STM lens, the EW-52 Lens Hood helps to minimize flare by deflecting stray light from entering the lens. The hood also provides additional protection to the lens from accidental impacts, bumps, or scratching.
Perfect fit for my Canon RF 35mm f/1.8, and it really helps cut down flare in bright outdoor shots. It also adds solid protection to the lens without feeling bulky. Excellent value and exactly what I needed.
