The BH-823 lens hood is designed for the Tokina AT-X 14-20 mm f/2 PRO DX lens and effectively blocks stray light that could enter the lens. This prevents lens reflections and ghosting, enhancing image contrast and clarity. Additionally, it serves as a protective barrier for the front lens element against accidental bumps, dust, and scratches, helping to maintain optical performance and extend the lens's lifespan. Made from durable materials, this lens hood ensures reliable performance under various shooting conditions. The bayonet mount allows for quick and secure attachment, and a locking mechanism prevents accidental detachment during use. Weighing approximately 45 g, it adds minimal weight to your camera gear, making it a practical accessory for photographers looking to make the most of their wide-angle lenses in landscape, architecture, and interior photography. This replacement lens hood is compatible exclusively with the specified Tokina model, ensuring a precise fit and optimal functionality.
