Lens hood is one of the most important accessories from each lens you own. A lens hood provides multiple functions: it shades the lens form stray light, improving your contrast and image quality; in inclement weather, it can assist in keeping moisture or wind-blown debris off the lens; and it protects the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles. It can be collapsed in to 3 styles for adjusting hood’s length. Extend it for telephoto shooting. Collapse it for wide angle shooting. Filters can be mounted on the hood directly without taking off itself from camera. Hood made of high quality silicone which can be collapsed easily.
