A must-have - actually.

I use the panel for six months in connection with the EF-S 18-200mm. The lens hood is firmly seated, is of high quality, and is doing in terms of protection effectively what you can expect from it. The velvety coating on the inside protects against unwanted reflections, by the shape tinted vignettes can be avoided.

What prevents the 5-star rating? While other lens manufacturers mitliefern the lens hood, you have it in Canon - despite higher prices lens - still buy. The aperture is indeed qualitatively better than their counterparts such as Tamron, that does not justify the asking price of Canon (75 for a piece of plastic!) Yet. Even for the 32 currently in the Amazon part is still overpriced tough.
