Panasonic DMW-EC5 Eyecup is a viewfinder frame for the Panasonic Lumix DC-GX9 Mirrorless Micro Four Thirds Digital Camera.

This eyecup is intended to prevent stray light, which could make focusing and composing an image difficult, from coming in between a compatible camera's viewfinder and the eye it is held up to. The cushioning it provides serves to promote comfort during use as well as to protect the surfaces of eyeglasses or sunglasses if they are worn while holding a compatible camera up to one's eye.
