I did 4 exposures with each camera, each exposure was 60 seconds long and was taken using ISO 1600, 3200, 6400, and 12800. All the exposures were done at room temperature with lossless RAW 14-bit format. All photos were exported through the latest version of Adobe Camera Raw with all noise reduction turned off. I increased the exposure compensation with a value of +3 on each photo to make the noise more visible.
Note: You can click each of the test photos below to see them in a larger size.
As a takeaway, we can see that the Nikon Z9 seems to perform really well, almost on par with the Nikon Z6 II and much better than the Nikon D850. I need to do further tests to see the performance out in the field, but this first quick test looks really promising.
