This SmallHD Focus is a top-mounted camera monitor that's compatible with Panasonic GH3, GH4, and GH5 cameras. It offers greatly enhanced brightness, enabling its 5.0", 1280 x 720 pixel screen to be easily read, even during bright daylight. It's tiltable, too, for more convenient viewing from various angles. In addition, should the need arise, the Focus, via its attached Sony L-series battery, can act as a power source for your Panasonic camera.
