The Lens Hood for M.ZUIKO Digital ED 75mm f/1.8 Lens from Olympus is a silver, metal, round-style lens hood specifically designed for the M.ZUIKO Digital ED 75mm f/1.8 lens by Olympus. Lens hoods prevent glare and stray sunlight from entering the lens while shooting and offer the lens a degree of protection from accidental impact and scratching. This lens hood attaches to the lens' filter thread and has a twist-lock mount for extra stability.
