Nikon DK-10 Rubber Eyecup

Designed for select Nikon DSLR and SLR cameras, the Nikon DK-10 Rubber Eyecup serves as a viewfinder frame. Its primary purpose is to prevent stray light from interfering with the viewfinder, ensuring ease of focusing and composing an image. The eyecup's cushioning not only enhances comfort during use but also safeguards the surfaces of eyeglasses or sunglasses, if worn, when the camera is held up to the eye.
