I had to examine before buying opportunity a replica lens shade of a friend and have to say that the 16 which has cost it's not worth it. I have then decided the original Canon to order and to bite the bullet of the "40 for plastics". Here I can only recommend to anyone the stock to buy, because it fits perfectly, is stable and has a sort of felt for matting on the inside. 40 are still nothing to sneeze at for a "piece of plastic" and certainly overpriced but there's really no alternative. Who pays for 600-700 euros for the lens should not skimp on the lens hood, because it contributes to better imaging performance at.
