Sorry to revive a long dead thread, Rich Brown. Did you ever complete these tests? It would be great to see a comparison.

Rec.2020 is great, if you have a capable monitor for accurate grading. But the article seems misleading when it talks about raw workflows. Doesn't shooting in S-Gamut3 and S-Gamut3.Cine on the FS7 (mk1), in any flavour of CODEC give you a larger colour space that can then be graded to rec.2020 for delivery?

Am I missing something? Because, all this means is that the mk2 can record rec.2020 natively for quick delivery, while the mk1 will still be a capable production camera when rec.2020 becomes more widespread – it'll just need a grade.
