Nikon Zr
That's it, the real news is here.
So it's definitely the Z6III sensor (6K), there's Redcode, BUT it's a 12-bit version (instead of 16), the extension is different (.R3D NE... "Nikon Edition"?), and you can't choose the compression. However, it comes with 3G10 Log (where you can shoot N-Log in N-Raw and other modes).
There's NO fan, you can only shoot in 16:9 (no Open Gate, no 17:9), the camera menus are the same as usual for Nikon (so no RED menus), and there's no anamorphic support either.
32-bit float sound compatibility (with external accessories), there's IBIS, and a 4-inch screen (that's more convenient!).
Finally, the media: CF Express and microSD (so the rumor was wrong about SD instead of CF Express Type B).
no ventilation, which is bound to be a problem in the long term.
It's a big disappointment that the menus remain the same or that we don't have the option of more adequate measuring tools (especially RED's GioScopes).
