Abstract
Abstract A remote camera viewfinder has a fiber optic bundle with a fitting at one end adapted to attach to the eyepiece of a camera and a fitting at the other end for allowing a photographer to see through the fiber optic bundle. The camera end fitting has a lens for focusing the image onto the focal plane of the fiber optic bundle. The other fitting includes a lens adjacent to the end of the fiber optic bundle to magnify the image transmitted through the bundle and also includes an eyecup mounted to a helmet or headgear arrangement which holds the eyecup adjacent to the photographer's eye allowing both hands free for manipulation of the camera.
