This lightweight lens hood for three Sony lenses helps protect the cameras lens from impact shock and dust as well as prevent unwanted stray light from entering the lens by extending and shading the end of the lens. Specially designed and made of industrial grade anodized aluminum, this hood is ideal for everyone using these lenses. Inspired by the Leica design, the rectangle shape will cut overhead glare and significantly lowers the chance of vignetting at wide angles. With its matt black, stepped interior, the lens hood is designed to reduce glare for a cleaner, clearer picture and the professional, sleek design adds a classy edge to this useful tool.
