The 72mm Lens Hood for ND Fader Circular Filter System from Genustech is a dedicated three stage lens hood for the 72mm Genus ND Fader Filter. This rubber lens hood with built-in screw mount attaches directly onto the neutral density filter which then screw mounts onto the lens. As the filter is rotated for varing degrees of light reduction, the hood rotates with it.
Lens hoods are designed to shade the end of the lens and prevent unwanted light from entering the lens causing flare. They also offer a degree of protection to the lens from accidental impact and the elements. This 72mm lens hood is a flexible three stage hood which can collapse or expand to provide three lengths with three degrees of light control.
