Doug, what raw developer do you use? FlexColor or Capture One? Lightroom is getting pink reds...

FWIW, I have now an R8, a DMR and I temporarily converted my 35 Lux back to Leica mount to try it all out.

You know that is useless if the sensor can't provide enough tonal range/precision to make use of those 16 bits, right? Converting the RAW of any 12 or 14 bits camera a 16 bits image in PS will give you more data to PP if that camera has better tonal range, AFAIK.

I think you're seeing what you expect to see. There are lots of variable involved here including lighting and my processing.

I also see a tiny bit of pink there, but I think the bird could easily have been that colour. We need photos of standard objects here, like Ferraris or Coca Cola cans I have the camera with me today and will try to make a few photos of items of well-known colours.

I see red shifting toward magenta.
But that can be addressed using HSL or levels...if so preferred, of course

Pink, magenta... Pink is after all only red with a bit of white. Anyway, my daughter has a scooter which is fire-engine red, and when I took a photo of it, it came out a little pink (my D800 makes it a little orange, and a 5DII I tried even more so). I should try the Fuji S5 on that scooter

Anyway, I will try a few more constellations of red with the DMR today and see how that goes.

Ok, it's CPYK then
How about luminosity of the surface you are shooting?

Not sure what portion of the scene you believe you are seeing the shift toward magenta, but the image is in mixed lighting that transitions from warm to cool. Probably not a good image / lighting to be evaluating color accuracy in mixed lighting.

Ach, don't be sad about the Ferrari, they aren't worth the trouble until you are wealthy enough to have several such cars. What I really want is an arctic silver 70s Porsche 911, which can be had in decent shape for 15000 Euro or less, quite realistic, even on a restricted budget.

Perhaps we are using a different camera profile?

Yep, Porsche..

In that particular "bird" pic I think its just light. That point with Coca-Cola is good, their red is super-consistent.

What I'd really like is a VW Synchro Westfalia but what I can afford is a 17-year-old ex-Forest Service 4x4 pickup truck:

With a nice work cap and good color balance.
