GX85
Apart the Japanese menus and to invariably miss the much professional interface design because simplicity is to excel the filmmaking norm matching a superior IQ quality of my P4K, I love my GX85 and my three GH1 units as well, great cams, will never sell not even one of them ; ) Yet on 1080 fence, my two GF5 units instead look like even smaller toys made of dreamlike and reliable standards anyway. Wonderful tiny capture device format factor BTW. MFT is the best format ever, let alone the incredible unique light glass itself when not for peanuts price : P
If you'd just want a 4K bargain to add to your arsenal, buy the G7 (I only have four of them! LOL : ) you'll be able to get in the range of 300-400 bucks.
On those words, I just try to resume the framework which grounds my MFT option route. I confess : D cams are an addition, so we need to buy good for affordable... : X
E : -)
