This lens hood is designed to prevent stray light from entering the lens, reducing flare and haze when shooting in backlight, sidelight, flash, or at night. It also helps block ambient scattered light when shooting in front light and sidelight. Furthermore, it minimizes distracting light from entering the lens when shooting in bright light or at night. Beyond light control, the lens hood protects the lens from scratches, fingerprints, and, to some extent, wind, sand, rain, and snow. Easy to install and remove, and reversible for convenient storage.
