To be clear, STARVIS is a new sensor whose technology is mostly meant for applications in scientific, industrial, and security spaces. And Sony won't give out any "normal" number with respect to ISO yet, either. Part of that might be because actual ISO is difficult to determine, since the back-lit CMOS sensor places its photodiodes in front of other hardware components that, conventionally, would block a substantial portion of light information. But as unclear as the exact results are, here, the latest advancements in ultra-sensitive sensor trickery point to a new level of attainability.
