The dedicated Haida X100 lens hood is designed specifically for use with Fujifilm X100 Series digital cameras. It is mainly used to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. A dedicated hood is designed to perfectly fit the specific focal length of the lens it is designed for. Additionally, this hood features an anti-glare matte finish on the inner surface to further prevent or limit lens flare. Plus, since the end of the camera extends, you get the added benefit of extra protection against accidental impacts. The thread is designed to also work with X100 clear filter/1/4 black fog filter. To match the color of the camera, the aluminum filter ring is designed in two colors: black and silver. When you achieve this, the aesthetics of the camera will increase.
