Query: Useless

I don't recommend this product. Much better lens hoods are available to protect your investment than this. I purchased the camera armor and figured I would get this also. The Camera Armor is worth the money it never leaves my Canon 50D that I take everywhere with me and works great. The lens hood Does not fit on my senses well and prevents some of them from working correctly.
