Hi,

I try to create bias frames with a Nikon z6. But the bias frames have not the correct (shortest) exposure time, for example the filename is Bias_0.000250_secs_001.nef which shows the correct exposure time. But the exposure is only 1/15 instead of 1/8000. Same, if I choose 1 second. Examples below. I double checked this issue with a Nikon D750 - the exposure time is the shortest one for this model (1/4000). Does anybody knows a workaround for the z6? Or is it a bug? 

Kstars 3.5.2 Stable
Linux (armv7l) release 5.10.17-v7l+

Thanks and best regards,
Mirko
