While the full-frame 1080p/4K a7S from Sony is proving to be an absolute beast in low-light situations, it's far more than just a night-shooting camera. Besides resolving what looks like a very solid 1080p image (an external recorder is required for 4K), it's also got some pretty fantastic dynamic range. How good? Well the folks over at cinema5D took the camera for a spin, and measured it at over 14 stops, right next to the ARRI AMIRA, which uses the same sensor as the even higher-end ALEXA, which is being used on tons of Hollywood and indie features.
If you missed it, here is how good the camera is in low-light (courtesy of Philip Bloom):
