Are these new JVC cameras supposed to be a 4K DSLR look kind of camera? I assume you get no lens controls with them.

They have an active m43 mount, so you get stabilization and control with panasonic lenses or Canon with an adapter, Olympus will be there too but no stabilization and nothing at all with the rest.

I'm very interested in this camera. We have to wait if the blown highlights are just a problem of using prototypes or if it will be in the production version.

Looks interesting. The production model also had cinema mode (no idea if retail version will have log mode as well).
