Excerpt: Do yourself a favor and spend the extra few follars for this Canon product instead of an aftermarket lens hood. It's better made and more importantly goes on and off with ease without those nasty scuff marks the ill fitting aftermarket ones seem to always leave behind.
Excerpt: I ordered this OEM lens hood after owning an aftermarket hood for years. Take it from me, spend the extra few dollars and buy this one. The picture quality is better; especially when shooting into the direction of bright sunlight. This is due to the coating on the inside of the hood.
