And thanks to your early support we were able to actually build the AXIOM Alpha prototype and get to where we are today!
And I'd like to know just how raw can be transported over HDMI. I thought HDMI required RGB or YCbCr encoding.
At this first stage we will not do internal video recording (only 4K RAW still images to microSD cards).
For video recording we rely on external recorders.
With the triple HDMI shield you can have up to 1080p60 4:4:4 on each port. With the Alpha prototype did not manage to get any recording device that even support 60FPS over HDMI but I am sure that will change soon in the future.
Same with 4K recorders, the Atomos Shogun is not available yet but once it is we will check which modes it supports and how we can support those modes in the AXIOM Beta.
RAW over HDMI we envision to work like this:
A single 24Bit 4:4:4 (8bit per channel) pixel can actually store the value of two 12bit RAW pixels (2x 12bit = 24bit). So with 1080p60 we could already store 12bit UHD RAW 30 FPS video.
The image just needs to be properly interpreted in post production but that you need to do with any raw format anyway.
On another HDMI port you can at the same time output a normal RGB 1080p signal so you see what you are shooting.
As this is untested we call it "experimental format"
Thanks for the explanation, Sebastian. Can you shed any light on the performance of the CMV12000? Specifically, does the pseudologarithmic curve really result in stroby highlights? How light sensitive is the sensor? Reports on the BMPC indicate that its low-light performance is poor (i.e., native ISO is maybe around 200 and noise becomes pretty bad above 800).At this first stage we will not do internal video recording (only 4K RAW still images to microSD cards).

BTW 16mm and monochrome sensor options added https://images.indiegogo.com/file_attachments/893944/files/20140930134526-axiom-beta-options-03.jpg
That's unfortunate -- why do we need systemd on a camera? A better choice would have been Tiny Core, Slackware, Gentoo, etc.
