@araucaria - The grade is a custom one, from a short film I'm making now. I like the Impulz LUTs, I used them as reference, though I agree that they can be a bit strong. But yeah, I boosted the red gamma in the shadows ;-)
@JohnBarlow - Yeah I'm interested, can you tell me more? How does the single focus modification work?
I was actually planning to 3d-print a set of custom gear wheels to rack double-focus on both Kowa and taking lens (already measured + drawn up, just need to design an extra bracket arm to mount the gears on the follow focus)
