The Multi-Power Battery Pack MB-D200 is ergonomically designed for extended stability and potential for vertical shooting. It runs either on AA-size batteries or 2x EN-EL3e batteries. When 2 EN-EL3e batteries are used, power is sequentially consumed, so the battery exhausted first can be replaced independently. It has an extra main- and sub command dial and alternative buttons for shutter release and AF start. The MB-D200 weighs approx. 230g and its dimensions are approx. 147.5 (W) x 72.5 (D) x 110 (H) mm.
