>>3410183Battery performance is about half that of sony, battery performance on sony has been a conatant point of criticism.
The nikons battery life isn't yet the top talking point for failure, because it has so many other, more important issues to fix first.
Also, consider what lenses nikon is looking to release, the first 3-4 years is going to be their most expensive lenses, and their roadmap shows that they develop lenses at about half the speed of sony, and they are not releasing the mount spec so don't expect native performance from non oem lenses and don't expect af adapters in a hurry.
Lowlight is a bit worse than the equivalent sonys, af is trash in comparison.
>>3410386Hence why there's cipa test standards for battery life to keep it consistent. Sony are about twice as good as canikon right now, and that makes sense, sony are the only camera company to make their sensors and mainboards, allowing them to maximise efficiency and size.
