Re: Suggestions for Panasonic? Let's hear them!
Add a swiveling screen as per G3 to the GX1, plus wireless flash control and a real optical viewfinder as per Fuji, more in camera filter effects, improved battery life.
Make the handgrips on the cameras both removable and interchangeable to cater for holding preferences.
An equivalent Panasonic camera like the new OM-D at the top of the family range/line.
More reasonably priced lenses for us ordinary folk on a restricted budget.
