Query: Too expensive

This lens hood is a must if you are serious about macro photography with you 100mm f/2.8. I cannot praise the lens high enough, but that is no reason why Canon should rip us off, asking $40 for a piece of cheap plastic!! Why don't they follow Nikon's example and start shipping their lenses with hoods. After all, good and pricey lenses are for people who are serious about photography, and people who are serious about photography want to have hoods on their lenses!! So Canon, stop being greedy...I give it a rating of 1/5 simply because the quality/price ratio is terrible.
