Universal Wide-angle Viewfinder M
Shoe-mounted External Viewfinder for M-system Rangefinder Cameras
The Leica Universal Wide-angle Viewfinder M is a shoe-mounted external viewfinder for M-system rangefinder cameras (including M8) that offers bright-line frames to match the 16-18-21mm lens, and other wide angle lenses within this range. A parallax compensation dial allows for adjustment of the frame to the focusing distance, in five steps (0.5, 0.7, 1, 2 meter & infinity).
The viewfinder uses one aspherical lens element and one with achromatic correction to provide a bright, high resolution image. An illuminated spirit level helps to keep the camera horizontal, and the eyepiece has a screw mount for optionally available diopter correction lenses.
