It's a shame and is repeatedly criticized annoying that Canon mitliefert with the lenses (except for the L lenses) the lens hood for free. I have yet to buy always easy grudgingly the expensive original lens hoods to a princely sum. Now I have - slightly hesitantly - resorted to the Walimexblende and was not only surprised but also thrilled: quality and feel to Origninal my feeling geleichwertig, fit top, no difference compared to my other original iris identifiable and the best, the inside the lens hood is similar in relation to the original with a black fleece, ie flocculated. I highly recommend this lens hood (actually Streulichtblende) only recommend, because it offers the same quality, feel and fit as the original half-price.
