If the IQ is comparable to Ricoh GRD III, I'd be happy.
Sony HX100 doesn't have RAW, does it? The lens is also 1 to 2 stops slower at ~50mm equivalent, no? For me, they are in different categories.
I am not too concerned about IQ. I am more concerned about manual focus implementation. It's about the photos you want to create. IQ isn't the only thing (but gear forums are usually biased).
For 40mm to 50mm equivalent, faster than f/2, small sensor for large DOF (relatively small prints), RAW, optical VF, IS, small form factor, I am not aware of another option. If manual focus is not implemented well for zone focus, then it would be sad.
Basically, I want a 40mm to 50mm equivalent GRD. For now, the Q comes the closest. I will let you guys know how it goes once the camera shows up.
What I am after is likely quite niche though.
