I discovered another flaw with the Z7 lens adapter. It took over a month of providing documentation and a bottle of blood pressure modification for someone to contact me that I had discovered an "unknown" problem.
The issue is with the slow motion in the video mode (even after their LAST update), but ONLY on the DX lenses. You can video slomo but not with a DX lens. They told me they would update their advertising to indicate that.
It never happened because a few months later the Nikon Z7 was discontinued along with support. (geerrr)
So please pass this on as those buying a used one may never know or feel they were duped.
