An on-camera monitor can be a tremendously valuable tool for professional video production. Most cameras have a built-in display, but often times a camera’s built-in display is rather small and—especially when it comes to shooting with HDSLRs—they are sometimes fixed in one position on the back of the camera. An on-camera monitor will provide a larger and higher-quality picture.
Way back—five years ago—if you shot video, you used a video camera, and if you shot photographs, you used a still camera. Today, that distinction is all but meaningless. Almost every video camera today captures stills, and virtually every still camera now shoots video.
