Made of high quality materials, 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 D600 battery pack, the camera can be powered by one or two En-EL15 batteries (one battery in the grip, the other in the camera), or by using six AA batteries. Using two batteries, you can combine cells from different manufacturers and with different capacities. The camera will then draw power first from one battery then from the other. The shape and design of the device have been selected so as to ensure the greatest comfort during shooting in both the horizontal and vertical arrangement. The handle is covered with a special rubber material, which ensures a comfortable and very secure grip. In its bottom part there is also a thread for mounting the camera on a tripod. The battery pack allows you to hold the camera better, improves the ease of use when taking photos in a vertical arrangement, and allows you to increase the number of photos that can be taken with one set of batteries.
