This about to be released remote grip for the Z cameras is, IMO, reasonably priced and a great asset to videographers and still photographers as well. It has an ARRI Rosette built-in and emulates most of the buttons, etc. on the Z Cameras. It claims it works on the Z6 II, Z7 II, and the Z9. It is not clear if it works on the Z6 and Z7, earlier versions.
I ordered one immediately and have a video rig all set to use it. There are various inexpensive ARRI Rosette attachments for any 15mm rails, etc.
It uses a USB-C cable (both ends), so some care is needed to not disturb the cabling, since they don't lock on.
