Thank you for your advise !
The only thing ( thats too bad ! ) with the G6 is that dual function thumb wheel. It feels really cheap and I found that it hard to move since it s really small and plasticky , also it switch from aperture to shutter speed when you try to set up one or they other quite easily. Maybe I had try a demo that had to much wear. So maybe it s better I wait a bit to see and try the Sony and compare to the other models. I was curious also to know why Andrew mention
This is arguably the best current ‘cheap’ camera for video, de-throning the GH2 and GH3.
So i guess I still have to do my homework !
Thank you!
