PSA: the Nikon Z7 III specs currently circulating the Web are fake/made up. Please move on and do not support or give any clicks to websites that have a long history of making up non-existing products. The Nikon Z8 will be announced first (obvious now) and I already reported that I have not seen anything reliable on the Z6III/Z7III:
If the Nikon Z6 III camera is coming soon, I have not heard about it
If something changes, you will be the first to know.
