Canon BATTERY GRIP BG-E20

The Canon BG-E20 Battery Grip is an optional battery grip with improved ergonomics designed specifically for the Canon EOS 5D Mark IV. It allows users to load a choice of one or two LP-E6LP-E6N battery packs. With two packs, the already-impressive battery life is doubled, compared to using a single LP-E6 pack in-camera. This is especially useful when taking advantage of the camera's movie mode or Live View mode – operating modes that use more power. The battery grip is constructed from magnesium alloy to match that of the 5D Mark IV and is both dust- and water-resistant. Additionally, it features a camera alignment pin hole for use with certain video heads and quick release plates. The BG-E20 also provides full vertical shooting controls, which can be independently turned on or off as the photographer needs to enhance camera handling, especially for shooting vertical pictures. It has a large number of operating controls as well: shutter button, multi-controller, AF point selection button.
