I have just bought a mint used Ricoh GX100. I was attracted by its design as a serious camera rather than just a point & shoot. Sort of a cheap digital Leica.
So far the results have been mixed. I am mostly struggling to get sharp shots. I had a suggestion that I should think differently; with such a small sensor shooting at f/10 does not help with DOF or sharpness. Rather shoot wide open. I have done so and the results are much better.
It also seems to be better shooting at arms length rather than using the VF1 electronic viewfinder.
Below are some test shots.
