Nikon Z6 III sensor readout speed measurements
My name is Adam and go by “horshack” on dpreview. This year I started a crowd-source project on GitHub for measuring the sensor readout speeds for as many cameras as possible. The methodology involves custom firmware running on an inexpensive Arduino board that flashes its built-in LED at a known frequency, which is then photographed and videoed in each of the camera’s photo and video modes to calculate the readout speed from the number of bands that appear in the captured image. The GitHub repository includes a deep dive into how rolling shutters work, plus instructions and source code you can use to perform your own measurements.
The project’s home page is at:

The live results page for the project is at:

For example, here are the different camera sensor readout speeds combined results (full-sensor, milliseconds):
