Dave, the battery is half the Ah (7.3 vs 14) of the Nikon EN EL 15, but also smaller in size and has to power a lot more. High resolution EVF, in-camera-stabilisation, pumping 23 images of 42 MP until buffer's filled... Wait, 23 full size RAW? When did you manage to get this many out of a Nikon / Canon similar in resolution? 5fps might not look much, right, and the A7SII, although much less MP doesn't deliver more. But for landscape and portrait it's already enough.


Anyway, the small batteries are the result of people like us always complaining about big fat cams and heavy lenses now it is smaller and that comes at a price.
