If your looking for a lens hood for your Canon EF22-55 lens, Canon says it is an EW 60D, but these are very hard to find and are usually expensive.

alternatively you can use a Canon (or third party) EW 60C which fits perfectly well and can be found for a few pounds, not sure of the actual difference as i've not been able to find a EW 60D to compare it with, if anyone could tell me i would be most grateful.
