As I write this, two bottom plates exist for the Zf:
- Nikon’s own ZF-GR1. This is an extended grip that is available only in Asia as far as I know. You can find them on eBay. The bottom plate just extends the bottom, it does not provide an Arca-Swiss dovetail.
- Smallrig’s 4262 grip [affiliate link]. This is an Arca-Swiss dovetail plate with an extended grip on the right front.
