My aim in this thread is to start a source of information on the specs - and perhaps more important to see what it can do that has not been done before.
For starters this 7.5 minute video
clarifies a very significant upgrade from the original body.
At £850 in the UK for the body with a free camera bag and the 2 DX lenses with in lens VR at decent package prices I anticipate it is going to stir up the content creators and lower price market - and that it will attract many new photographers to the Nikon system.
It is great to have the Expeed 7 in the little body of the Z50 II. But it seems certain, according to the proved inexistence of free lunches, that battery life will be severely impacted.
For me, that's a decent price to pay. No disaster here but I don't think one battery will be enough for a full day of photographing (a mere 200 or 300 max pics on a crazy day)
Double that, Brughel. CIPA tests involve using the flash on every shot, I believe.
According to :
Standard of the Camera & Imaging Products Association
CIPA DC-002-Translation – 2020
SStandard Procedure for Measuring
Digital Still Camera Battery Consumption
2.5 Flash photography Full illumination flash shall be used for one of every two pictures taken. For the other pictures, the flash shall not be used.
So it is half the "double" you mention. (assuming that "the flash consumes as much power than a pic without the flash")
In any case, the EN EL 25 is rated at 350 (CIPA) (which I dont believe I EVER reached) The Z50II is rated at 250. That's a good drop from 350.
Time will tell, but I expect a second, fully charged battery will be necessary.
I do hope to be wrong.
