A quick and dirty sensor stress test.
There had been a great deal of discussions on the Blackmagic forums about how the Blackmagic Cinema Camera performs when under exposed in lowlight conditions (http://forum.blackmagicdesign.com/viewtopic.php?f=2&t=4269). This test was based on those discussions.

We used the Sony NEX-FS100, recording to ProRes HQ via an Atomos Ninja 2, as known refrences for comparison. All shots were underexposed by over 2 stops.

No noise reduction was done in post and there is a rolling noise pattern in the BMCC footage but at over 2 stops under exposed I’d expect to see sensor take strain.
