I've had my two Nikon Z9's for a couple of months now. I've used them for over 10k shots so far. I'm experienced D6, D5 shooter and have had two latest Flagship cameras for the past 20 years.
I have had my Z9's freeze up twice on me where I had to pull battery to reset. Both times the camera wasn't lighting up, preview, EVF or any response to any input. No error message either.
I found this one corrupt file within a 1900 image shoot. When viewing in Adobe Bridge, I can see the thumbnail for a split second, then the bottom 2/3rds of the image goes black. When you open the file up, it's 2/3rds black.
I've sent to NPS support but of course, no response.
here's a dropbox link to the image https://www.dropbox.com/s/gdy2mw7rerexapp/004-22-102.NEF?dl=0
nice. Not that it matters. that was part my test shot before capturing the image w people in line and getting food. It's weird though that the nef didn't record fully.
I wondered if I turned camera off too soon but all the D cameras would finish writing the file before shutting down.
I'm still shooting test shots like with the D series because I haven't totally trusted the preview EVF yet.
I'm also finding that using Auto ISO or any auto exposure functions, Im' a good 2/3-1 stop under. That doesn't work well at over 6400iso. I'm back to manual everything except focus like I've shot for decades. It's easy.
Thanks for the feedback though.
When I have had these problems it was with defective memory cards. If the camera cannot write to the card the firmware does not recover and have the memory card write to a different sector. A bad sector or a card that is too slow with data writes from the camera will cause problems.
