Compatible with multiple lens sizes: This flower-shaped lens hood is designed to fit a variety of camera lenses with front filter threads, including 49 mm, 52 mm, 55 mm, and more. You can use it with your favorite lenses. Anti-reflective coating: The interior features an anti-reflective coating that effectively minimizes unwanted reflections and stray light, helping preserve image contrast even in challenging light. Protective design: The flower-crown shape not only directs light properly into the lens but also serves as a protective barrier against scratches and damage during storage or lens changes. Easy screw-on mounting: A user-friendly screw-on mounting system makes attaching and removing the hood quick and straightforward, for photographer convenience. Practical applications: - Outdoor photography in bright sun (landscapes, cityscapes) to reduce flare and maintain contrast. - Backlit or side-lit subjects (portraits, events) to control stray light. - Travel or field use where front-element protection is beneficial during storage or lens changes.
