Hello everybody,
First contact this afternoon with a G9: besides all what was already said about Raw, resolution,... I will just add that it seems that it is a little bit faster (switching on, activation of the menu/option, and also focus). Of course this is just a feeling (but I was using the G7 in the past) and not lab measures.
Then I tried with my Ikelite housing (designed for a G7). No problem to mount the camera, to switch on and to activate zooming or to take pictures, but some controls were not accessible and will not allow to use existing housing (all the buttons on the back have moved from 5mm to the left).
So now I have to find a G7 or to sell my housing...
regards
