I brought this for my 18-200mm Canon zoom lens with 72mm fitting, and it works perfectly, it's a nice quality with a matt flek finish inside, it fits backwards onto the lens for when not in use or easy storage, and is easy and quick to fit and remove with a 90 degree turn and fitting is secure and positive. the only downside is it causes a darker shadow at the bottom of the picture with the flash if you leave it fitted, a little expensive, but for a quality item that'll last the life of your lens it's probably about worth it.
