Adapter, 4/3 to m4/3!

The preconceived idea that an m43 camera HAS to be small is just about that - a preconceived idea. The GH3 being a good example, as you point it out.

I am not giving up on the hopes of seeing something really modular someday, the HLD-6 grip with its two modules being a step in the right direction.

Something more elaborate ending up in a decent form factor would be an interesting thing to try.

Automatic translations from Japanese being what they are - I am intrigued by the "Actuator" part. No Olympus digital lenses need an actuator.

If this is what I think it is - this adapter would actually have some sort of optical elements which would be the ones doing the actual focusing ?

If yes, this comes very close to my dream of yore (pre- micro four thirds) about a system which would do some sort of "slow" ballpark prefocusing on the lens itself, then a fast focusing at the sensor level, like some old Contax cameras did (although their focusing by moving the film plane was anything but fast, then again the mass to move was totally different).
