So as an owner of the Nikon Zf, unless you hate your hands you most likely have to pick up a 3rd party grip such as the one from SmallRigs.
The issue I'm having, which might be unique to me, is that it makes it hard to pull out the memory card due to the lip the grip adds on the bottom.
So I came up with an easy fix. Hope it helps!
