The newly released, top-of-their-line, Nikon Z9: > Well, IMATEST confirms the observation from the waveform plot above: there are about 12.7 stops max. dynamic range, but nothing more. Also, in the middle graph above the blue “12.7” line (indicating SNR = 1), there is nothing. > If we look at the measured gamma curve (first graph in the IMATEST result above) – which is the used N-Log profile – it becomes obvious what is happening. N-Log as it is designed for now cannot hold more than 13 stops. If you look at the distribution of stops on the shadow side (to the left), there is a more or less horizontal line – meaning, that there is no code value differentiation between shadow stops anymore. * https://www.cined.com/nikon-z-9-lab-test-rolling-shutter-dynamic-range-and-latitude-test/ https://www.cined.com/nikon-z-9-lab-test-rolling-shutter-dyn...

from the article: >However, dynamic range results stay below expectations – the Z 9 shows about 1.5 stops less dynamic range than its competitors from Sony and Panasonic. That implies "its competitors" have a dynamic range of around 14.2 stops, which would put it above film cameras. Moreover, I'm wary of comparing values like "stops" between various sources. In the two sources you provided, the Nikon Z9 has either 12.7 stops or 11.3 stops. That seems like a pretty big difference, especially if the original source says that the difference between film and digital is only 1. Are there any dynamic range measurements for film and digital cameras from the same source?

  Those 14 stops are at ISO 50: * https://www.dxomark.com/sony-a1-sensor-review-speed-and-quality-in-one/ https://www.dxomark.com/sony-a1-sensor-review-speed-and-qual... Once you get in the ISO 200-400 range, things stop dropping.

Another factor to add into the mix is HDR with digital, and being able to combine multiple exposures in one.
