Launching a couple cube cameras that can be rigged for super high ISO work, Canon announced the ML-100 and the ML-105. They’re really meant for niche applications, like super-low-light industrial use. They can “see” in color at 0.0005 lux, which is technically the equivalent of the light levels seen after being swallowed by a whale before lighting your cartoon candle.
Other than having a Super-35-sized sensor, suggesting video use, there isn’t much more information on specs, pricing or availability.
