Lens Hood A lens hood is a cylindrical or conical accessory that attaches to the front of a camera lens to block unwanted light from entering the lens and causing lens flare, ghosting, or reduced contrast in images. Lens hoods are designed to extend beyond the front element of the lens, shading it from direct sunlight, stray light, and other sources of glare.
By preventing extraneous light from hitting the lens at oblique angles, lens hoods help maintain optimal image quality, color saturation, and contrast, especially in bright outdoor conditions or when shooting towards the sun. Lens hoods come in various shapes and sizes to match specific lens designs and focal lengths. Some lens hoods are reversible or collapsible for compact storage when not in use. While lens hoods are primarily used to improve image quality, they also provide physical protection for the front lens element against accidental bumps, scratches, and damage. |
