One of the big challenges for any camera is the ability to shoot video in low light – it’s not impossible, but what you get is a grainy image that’s hard to make out. But Canon’s new ME20F-SH “multi-purpose camera” could change all that. The industrial, Full HD interchangeable lens camera can capture video with less than 0.0005 lux of illumination, which translates to an ISO sensitivity of more than 4,000,000 (that’s 4 million). To give you some sort of comparison, the latest DSLRs don’t even break 100,000.
