Enjoy longer shooting times and improved control in portrait orientation with the Canon BG-E20 Battery Grip for the EOS 5D Mark IV DSLR. Able to hold up to two LP-E6/LP-E6N Li-ion battery packs, this grip will effectively double your shooting time.
Also, it features vertically-positioned controls, including a shutter release button, a multi-controller, and an AF area selection button. 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.
