Excerpt: Hard plastic, felt-lined inside, clips on nicely and doesn't fall off. Honestly, I had an off-brand version of this for a few months and it really was awful, and then I lost it and decided to buy the real thing.
Pros: Durable, Easily Interchangeable, Lightweight, Rugged, Strong Construction
Excerpt: Love this little lens hood. It's a bit pricey as is usual with original Canon products but it is necessary for the 24-70mm lens. Without a lens hood I'm always worried about scratching the lens so this is well worth the price tag.
Excerpt: The hood is of good and durable quality. It feels flimsy when not on the camera though. It fits onto the 24-70mm f2.8 well, and the lens hood lock is a plus. It is easily interchangeable. Overall a decent hood, would've given 5 stars if not for the price.
Excerpt: The hood will not stay attached to the lens. The retaining button is worthless and the hood fits poorly on the lens. I own 9 "L" lenses and this hood is the absolute worst of them all. A big disappointment.
