Vivitar 77mm Professional Tulip Hard Lens Hood
Protect your lens and get increased image quality.
The Vivitar 77mm Pro Hard Lens Hood is primarily designed to prevent unwanted stray light (flare) from entering the lens by extending and shading the end of the lens. In addition, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact.
Screw-mount lens hoods, such as this 77mm, are designed to screw right onto your lens or filter. A rear locking ring allows the user to rotate the hood 360 degrees.
