Sony FDA-V1K Optical Viewfinder

The Sony FDA-V1K Optical Viewfinder is an external viewfinder for use with the Sony Cyber-shot RX1 compact digital camera. Featuring Carl Zeiss optics, this viewfinder provides a bright clear view that matches the angle of view of the camera's built-in 35mm lens. An optical viewfinder is especially helpful for finding and tracking of fast-moving subjects.
