What Andrew said! That would be my Holy Grail camera. No video, no art modes, just a camera capable of recording high quality images with minimum fuss. A leaf shutter instead of one like a thunderclap would be nice.
I have been playing around in my mind with the idea of a modern camera that has a dedicated aperture dial on the top plate, like the film GRs. I change aperture a lot more often than SS, and on-lens aperture rings are kind of finicky. A nice compact dial on top would be rather nice.
