Thanks for that thought.
I'd like to communicate directly to EF lenses, yes.
I'm sure the FZ mount on the F3 is physically the same as F5/55, just wondering if the software in the F3 will control the very new Metabones FZ - EF. Metabones site only states 'tested on F5/55', although other sources (including B&H) suggest it should work on all FZ mounts.
Just want to be sure before shelling out $1000 USD's.
I've emailed Metabones, so hopefully I'll get a reply.
Thanks Macks!
