And it is becoming clearly apparent that this camera's micro 4/3rds sensor isn't a huge fan of anything thats remotely underlit, and thats with a 1.8 lens too. I've conducted some low light external tests with it because a scene I'm shooting is set at night, and I tested various ISO's. 200, and 400 barely gave me a picture, and 800 and 1600 introduced a shedload of noise. So I am wondering, should I just OVER light my scenes, and take back the exposure a bit, either on the day or in post with Da Vinci Resolve using the Camera Raw function?
The Pocket camera does not use a m4/3 sensor, it has a smaller one than that. Also, the overall sensor size has no baring on its low light performance - that is dictated by many other factors and the only one pertaining to physical size is the size of the photosites - in this case they are actually quite large, larger than a 5D Mkii and Mkiii.
The Pocket camera uses a sensor from the same family as the BMCC, only that its resolution is lower and its size is equally scaled - it is as if the sensor was windowed to a 1920x1080 crop rather than 2400x1350 one.
On the BMCC I have managed to film with good results up to a rating of ISO 12,800 - which is pretty good and well outside of what I would consider to be adequate film lighting. The lower sensor resolution of the pocket camera will no doubt reduce the low light performance slightly - as a higher resolution does help to cope with noise - but not by a massive amount.
Example of a night time scene, it ONLY with street lighting - rated at ISO 12800

Some noise reduction has been applied in resolve - but as you can see the image still retains detail.
All this is by the by however - as lighting is the number 1 most important part of cinematography in my opinion - more important than good lenses and a good camera. Whilst cameras which are capable of shooting in low light do indeed open up extra possibilities and increased functionality, when one can light properly - one always should. Even scenes which are intended to look dark in the end need proper lighting, it is all about the lighting ratios and relative light levels, rather than the absolute values.
