About differences in exposure:

In my opinion on both cameras RAW exposure was set to best possible for such low light test. Both cameras were set to widest aperture and some predefined and reasonable shutter speed. So both cameras were able to change only ISO and yes - they picked ISO differently what caused ever-exposure for one camera BUT only for JPEG - not for RAW. ISO value is not affecting RAW at all. AFAIU it is just software post-multiplier and it is not affecting over- or under- exposure of RAW. So we took those "virgin" RAW files and adjusted brightness so that both images have about same exposure. Those 2 final images in the end have very close exposure (or brightness) and IMO they CAN be used for judgment about low light capabilities or RX-100 vs  NEX+kit combo (even if initial JPEG exposure was different of wrong)
