This rotating lens hood is designed for digital cameras with either built-in or interchangeable zoom lenses. The hood protects against stray light reflection hitting the surface of the lens, and at the same time will not vignette the corners when using the wide angle feature of the lens

The hood is not like a Canon lens hood. The Canon hoods use the molded large threads that are a part of the Canon lens that allows the hood to be reversed for storage. This cheap-o hood uses the fine threads in the lens assembly and will not mount in a reverse mode. A lens cap cannot be used when the lens hood is attached. Keeping the hood attached takes up room in a bag. I will bet the fine threads on the hood will be a real problem after the hood is attached and removed a few times. If you use a thin filter without much thread depth - good luck attaching the hood. The description says noting about this and I wasted $8.00 - this is too small of an amount to waste time with a return - but enough to make me feel cheated. Lesson learned - buy original mfg equipment.
