The GF9/GX850 is your simple, pitched at less involved user camera. Mobile phones have completely killed off simple compact cameras. There is no way that selling a phone at a good profit margin then giving a free camera with it can be beaten by a simple basic camera that costs "hundreds" of dollars and can be blown away by any half respecting mobile phone camera.
In effect the GX850 is a very capable camera - just a pity that it comes in sheeps clothing.
Cameras need to be proper cameras for those that are interested in them as a primary tool or die a death from mediocracy.
This is why the GX850, howeevr well it sells is sending out mixed messages. "Hey buy this fun camera, no real effort needed to use it ...."
People who buy "proper" cameras nowadays are enthusiasts who want control of ISO, aperture and shutter speed.
This means cameras need to have buttons and dials that fall easily to hand.
For that market, the GM5 is better than the GX850.
It will be interesting to see how well (or otherwise) the GX850 does in the market after a year or so.
