【Product Overview】Compatible hood for Nikon HN-40. The original is made of plastic, but this product is made of solid aluminum, machined from a single piece of metal, and painted silver. It matches the 16-50mm lens of the Z fc lens kit. 【Product Features】The inside of the hood is painted matte black to prevent internal reflections. A φ46 female thread is cut inside the hood, allowing you to attach a φ46mm lens protection filter (verified to not cause vignetting). When attaching a cap, you can attach the original lens cap inside the hood, but repeated use may cause the matte black paint to peel off. Therefore, instead of attaching the cap directly to the hood, attach the protection filter inside the hood and then attach the cap to the filter. 【Compatible Lenses】Compatible with the NIKKOR Z DX 16-50mm f/3.5-6.3 VR of the Z fc and Z50 lens kits. Other lenses may fit, but vignetting may occur, so please pay attention to the compatible lenses. 【Hood Benefits】A lens hood blocks unwanted light from outside the angle of view, preventing flare and ghosting, which can degrade image quality. It creates a comfortable shooting environment with an optimal shape for each lens. 【About the Manufacturer】F-Foto was founded in 2012.
