Hello fellow community :)

I know this is an old thread, but I just landed here searching for my problem.

If anyone is having problems taking images with a Nikon Z-series, and restarting everything does not help, there is a nice little detail about the mirrorless Nikons. When you unplug the power while the camera is on, the camera closes the mechanical front curtain (I have an external power-supply instead of the battery). The front curtain stays closed after the next power-on until you manually press the release button on the camera. While the mechanical shutter is closed the camera will not take any pictures or open the front curtain from software commands. You only recognize this in EKOS from capture errors and permanent retries.

A nice side effect is, that you protect your sensor from dust when you unplug the power after an imaging session :)
