I'm still looking for a small form factor large sensor camera with aps-c sized sensor and P&S type lens.
So far, the G1X is the closest. I've looked at the interchangable lens cameras, the lens sticks out too far, and my large fingers cannot feel or press the tiny controls. The touch screen might work better for me.
I reviewed several of the small mirrorless cameras again today. I also looked at the small sensor ones like the J1, V1, RS100 and did not see them working for me.
I'm sticking with my G11 until something comes along that I like better, I do not like the G11 for the small controls, but it was the best I could come up with.
Maybe a G13 with 1 inch sensor and touch screen ... Nah.
