The Hitachi GM-51 5-inch Video Camera Viewfinder is a professional broadcast viewfinder designed for use with Hitachi studio and field production cameras. It provides camera operators with a clear, stable reference image for precise framing, focusing, and exposure control during live broadcasts and recorded productions. Its compact 5-inch size makes it well-suited for both studio pedestal cameras and mobile OB or field camera setups.

Engineered for broadcast reliability, the GM-51 delivers consistent image performance with good contrast and sharpness, enabling operators to confidently monitor video signals under a wide range of lighting conditions. The viewfinder supports extended operating sessions and is ergonomically designed to reduce operator fatigue, which is essential during long production hours.

As part of Hitachi’s professional broadcast camera ecosystem, the GM-51 integrates seamlessly with compatible Hitachi camera systems. It remains widely used in legacy broadcast environments where dependable CRT or early LCD-based monitoring solutions are preferred for their real-time response and robustness.
