I just got my FS7 today and started to rig it up with the Zacuto VCT baseplate, but quickly realized that the rosette handle won't work because the baseplate is wider than the camera. When you try to screw the rosette arm with handgrip on it hits against the rod knob and the edge of the baseplate. Zacuto says they're working on a fix for the end of this month, but could take awhile. I'm a bit disappointed that they advertise the baseplate as working for every camera but didn't see this coming.
In the meantime, I'm going to try this:
