AKA as a bayer filter. Does anyone know how good this is? This is important for getting nice colours IE Skin tones.

I believe with raw the image is de-bayered in post - i.e. in Resolve. You have ALL the colour data stored in the codec.

Needless to say - very happy with the BMCC colour and skin tones so far!

Andrew Debayering has to be done at capture and the quality of the colour filter array will affect the image.. More expensive cameras use higher quality so I'd like to know what we are losing with the BMC.

How about downloading some footage and letting your eyes discern what you are or aren't losing?
I think it's important to trust your judgement and your craft more than specs.

Footage has to be viewed under controlled situations in order to compare. The BMC footage does look very good from what I've seen but I cant test one myself without buying it. One of the most important considerations and something I have written a thread on here is the difference ways film captures images to how digital captures images.

I would still prefer a 35mm movie camera image over an Alexa and thats probably down to the colour filter array and its shortcomings and thats on an Alexa. Obviously an Alexa will have a better array than the BMC you would think. But how much better and what does this mean in compromises to image quality.

The colour filter array is an IMPORTANT part of how good the image is With the BMC RAW its like sticking a porsche engine into a mini cooper. It all needs to be good or the sum of its parts will be the lowest common denominator.
