I wonder if the 14-bit depth could embrace the 15-stop dynamic range?  Would it be time for the 16-bit RAW for the 135-size sensor camera?

Even though the resolution of EVF is increased to 5.76MP, that of LCD remains rather lower 1.44MP, which may not improve the comfort for the manual focusing on the LCD.  Nikon Z6/7 offer 2.1MP LDC screens, and D850, a 2.36MP one.

I will be buying one when the dust settles in order to upgrade from my a7R II. I'm mostly interested in improvements in AF and responsiveness, though improvements in body styling are also nice. I'm excited by the new EVF as it should be significant improvement. Pity the rear LCD didn't improve, but the EVF is more important to me. The higher resolution will offer interesting possibilities when cropping.

Since the chip inside this camera is advanced, but is the same generation as II-III models, it will be overloaded with, probably about 12X, stream of info, so,  there will be  some problem with low light AF. The tracking under low light will be affected as well, as video Face tracking. This camera needs light, to be exact. What is the border level, is not clear yet. I think, close to -3, -4 EV. Great machine with some limitations, of course. Reality will tell, very soon. LZ
