The 82mm Genus Flexible Lens Hood from Genustech is a three stage lens hood that attaches to lenses or filters with 82mm diameter threads.
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 lens hood is a flexible three stage hood which can collapse or expand, providing three lengths with three degrees of light control.
The hood is compatible with the Eclipse 77mm ND filter.
