Vertical Battery Grip VG-XT4 The vertical battery grip is dust and moisture resistant and operates at temperatures as low as -10 degrees Celsius. It accommodates two batteries, and when combined with a third battery in the camera body, it offers up to approximately 1,450 frames in normal mode and 1,700 frames in economy mode. When one battery is exhausted, the camera seamlessly switches to the next battery while continuing to shoot, even in burst mode or during video recording. The grip features the shutter release button, focus lever, AEL button, AFON button, command dials, Q button, and Fn button to provide the same level of handling and comfort in vertical shooting as in horizontal operation.
