Like the smaller brother Z fc, the Zf allows using tripod attachments on the 105mm f/2.8 MC Nikkor Z and the lens can be rotated in any direction. This is not possible with the grip-enlarged Z5/6/7 or the Z9, the latter due to its battery pack. Not tried with the Z50, which probably won't allow free rotation, or the Z8 the latter I haven't tested in this regard.
It feels like a return to normalcy for me. Close-ups and 'macro' require tripod support for best results, and hanging the lens out from a camera mounted on a tripod is obviously not optimal. Not at all. A possible exception is with the Z9 as the lens is not heavy compared to the hefty camera body, so in this case the setup isn't that bad.
However nothing beats using a rotating tripod collar .... in case the shown collar is 'iShoot Duomianshou ZMC 105', which in stock configuration don't allow rotation. However, 5 minutes with a Dremel solves that "problem" easily. I replaced the large plastic lens hood with a no-name metal hood to make less interference near 1:1.
