C200: Why RAW? C200 12bits vs 8bits

I've never heard that, but I guess it makes sense. You can paint your picture with most professional cameras.

With builtin NDs, the camera manufacturer can perform corrections in-camera.

Software, as with Canon's Peripheral Illumination Correction.

As we all know, assumption is the mother of all mishaps… but for my part I've always assumed that any serious manufacturer would seize the opportunity to match each separate filter stage to its sensor. I've always thought of it as an additional advantage for cameras that have internal NDs, apart from just the convenience/sealing.

Especially with cameras like Canon's newer models where we see up to 10 stop worth of ND. It wouldn't be possible without careful tuning. And like you say: it might not be possible to make perfect filters in hardware at the higher NDs, but at least the in-house solution is a known quantity and can be further adjusted in software.

i have a theory that when you use any filters above 7 stops, you will end up with color shift and sometimes IR pollution, have you experienced that with your C300 ii?

Not that I've been looking out for it, but I haven't noticed it.

As a software guy, I suppose I'm projecting what seems obvious to me. Seems like low hanging fruit... This could be tested shooting color charts in IR source light (sun, heat lamps), right?

I can tell you for a fact that Canon has carefully engineered the internal ND systems, especially on the C300 MKII and C200 with careful glass selection, varying degrees of IR cut and how the ND affects the image. I've had conversations with engineers and manufacturer reps as well as Canon consultants who aren't employed by them and all agree on this.
