The Nikon HN-40 screw-on lens hood is designed for the NIKKOR Z DX 16-50 mm f3.5-6.3 VR lens and provides essential protection against stray light that could enter the optical system. This precision-crafted accessory effectively minimizes unwanted light reflections that can affect image quality, especially in challenging lighting conditions. The hood is made from durable black composite materials and offers reliable protection against scratches, minor impacts, and accidental touches during transport and use. The screw-on mechanism ensures a secure fit on compatible lenses without interfering with lens caps or filters. With a diameter of approximately 5.8 cm and a depth of 2.5 cm, this compact design maintains portability while providing optimal shading. The matte black interior coating effectively absorbs stray light and further reduces the potential for internal reflections and ghosting. Compatibility is limited exclusively to Nikon Z-Mount DX-format cameras with the specified lens. This accessory preserves the optical integrity of your photography system and provides practical physical protection for your valuable lens investment. The HN-40 represents Nikon's commitment to optical excellence through thoughtfully designed accessories that complement the performance features of their lens lineup.
