The GV-2 Mini External Viewfinder for more comfortable framing. LCDs on digital cameras are not always ideal for monitoring dark environments and fast-moving subjects. But the GV-2 mini optical viewfinder solves this problem. It mounts on the hot shoe almost directly above the lens and offers a framing guide equivalent to 28mm on a 35mm camera. It is even compatible with 1:1 aspect ratio image size photography.
