I ordered the Z9 on the day that it was announced in 2021. As yet I am still waiting in anticipation of delivery. If it is even half as good as the initial reviews suggest, then I will be very pleased.
The initial reaction to the announcement of the Z9 seems to have caught Nikon off-guard and they appear to be struggling to keep up with demand. I am resigned to not getting mine until well into 2022.
I will publish a short hands-on review here as soon as I receive it.
