The battery pack is equipped with a two-position shutter. Thanks to this, light pressure allows you to focus and pressing the trigger fully releases the shutter - just like in the camera itself. After using the Meike VG-B50AM battery pack, the camera can be powered from one or two NP-FM500H batteries. Using two batteries, you can combine cells from different manufacturers and with different capacities. The camera will then draw power first and then the other battery.
