Hello There. I admit to Article 5 stars because I am fully satisfied with the part. The Gegenlichtblenge is very well made and fits perfectly on my Nikkor 18-55 VR lens. The lens I can worn with Originandeckel despite visor. The lens hood can be opened in three stages. Level 1 for super-wide angle 24mm below, as I have seen in 18mm no shadows. Level 2 for focal lengths over 24mm, 24mm below you can already see the shadow. Level 3 for medium range from 35mm and telephoto, under 35mm focal length you can see shadows.
