The Canon ET-60 lens hood is primarily designed to reduce flare and protect the front element of specific EF and EF-S telephoto zoom lenses. It is compatible with Canon EF 75–300mm f/4–5.6 (III, II, USM), EF-S 55–250mm f/4–5.6 (IS, IS II), and EF 90–300mm lenses. It is not suitable for STM versions or the original 75-300mm.
