The lens hood is well made and fits like a glove. It sets the aperture to the existing marking in alignment with the second mark on the lens. A slight, but decent rotation by 90 ° and the panel snaps and budge. Furthermore, one can these with the same technology (but without alignment marks) mounted upside down. Thus, the panel does not project beyond the lens cap and can therefore be safely and compactly stowed in the camera bag.
About the price can be argued, but I will not let flow into my review, as you can see this before buying the product and should not depreciate.
I'm an image for this product upload, so they can see for yourself. I can in any case recommend the visor :)
EDIT: There are two images. I think so that everyone can make about a picture!
