I am a long term Lumix user, having had various G series cameras, and now the GH5. I love everything about it apart from that it does not perform well at all in low light. There are various minor functions I would love to see too. They are : - Less 'clicky' loud buttons.
Easy To Use; Nice Features and Settings; Rugged
Inaccurate Colours; Not Good In Low Light; Screen Too Small
