I received the product very quickly on 2.Werktag. Very good service. The lens hood makes up the abschraubaren locking rim a valuable impression. It is screwed on to the lens. This is somewhat tricky and requires some sensitivity. Once assembled, the aperture should remain on the lens as this offers several advantages. Scattering light is to be kept, so that the contrast and image sharpness. Furthermore, it protects the lens from moisture (raindrops, snowflakes, etc.). In addition, the lens is protected when it accidentally touches anything. Since the diaphragm is made of plastic, the panel deformed (as opposed to a metal litter lens hood) and prevents damage to the bayonet connection. Owners of cameras, in which the focus ring on the lens front turns should bear in mind that rotates along the detected lens hood. In my 55-250mm telephoto zoom the rash about from 10 clock bis 2 clock is being 12am the center position). I can not tell whether this represents a functional impairment of the lens hood. (Canon offers with different lenses aperture both tulips and cup for emphasis.) Tip: If you screw not overtighten the diaphragm, so you can easily align the lens hood when held fixed focus ring. I am pleased with the panel. Even the price is right, especially as a snap-on lid is that one can really use as a substitute.
