Hi! Here are some good quality screenshots from a clip that was posted in a BMPCC4k Facebook group. I have the footage in my HDD (12 GB for about 4 minutes), I may re-upload it (original link is gone), but I already feel like a thief writing this post ^^
The footage looks clean and beautiful. No visible noise, just a fine grain. It is not really representative of the final output of the camera but it looks very promising.
I graded it with FilmConvert and the BMPCC video preset. No sharpening, no noise reduction
