The dedicated Vello EW-78F Lens Hood is specifically designed for use with Canon's RF 24-240mm F4-6.3 IS USM lens. It is primarily used to prevent unwanted stray light from entering the lens by extending and shading the end of it. A dedicated hood is crafted to perfectly suit the specific focal length of the lens it is designed for. Additionally, this hood features a non-glare matte finish on the interior surface to further prevent or limit lens flare. Also, since the end of the lens is extended, you get the added benefit of some extra protection from accidental impact.

The "petal" shape of this lens hood maximizes the amount of hood coverage for the minimum amount of weight and hood area. The bayonet mount is designed to also work in the reversed position, allowing the hood to be placed backwards over the lens for a more compact storage solution.

Q: 1. so I bought this hood (for canon 10-22) and it snapped on quite nicely, BUT I can't seem to get it off?? I contacted support and they sent me instruction for a hood with tabs on the sides (obviously not helpful as this model doesn't have tabs - wish it did). Any help is appreciated as I don't want to break the lens (ugh!) - thanks!- Chris

A: Please do this at your own risk. I did not notice that it was very hard to get it off my lens. You feel as if you're going to break the lens. I would strongly suggest that you spend the money to get the Canon brand one. It was worth the investment. I used to buy Vello brand lens hoods before, but I have since stopped.
