A new 4K camera needs crowd funding. The specs at least of the sensor are impressive. 12Mp, global shutter 15 stops. Along comes something like dynamic range controller.

Neat thinking but kind of confusing site.

There is already a Alpha camera prototype:

A new 4K camera needs crowd funding. The specs at least of the sensor are impressive. 12Mp, global shutter 15 stops. Along comes something like dynamic range controller.
Apertus first announced the Axiom more than a year ago, but its highly modular design is definitely new. Its sensor, the CMOSIS CMV12000, has a 10-stop native dynamic range. According to Apertus, additional DR will be effected through a pseudo log curve, one of the sensor's three HDR modes. Arguably, its most notable feature is a global shutter (and, in fact, it has no rolling-shutter mode). We should be able to tell what the CMV12000 is capable of when the BMD 4K camera is released.

Do they share the same sensor?

Looks like it, although BMD hasn't said which sensor it's using. The specs -- including global-only shutter -- line up, however.

Blackmagic actually dropped the ball by not supporting 60p. The only 60fps readout mode is 60i...
Hopefully this might offer up to 4K RAW at 60p. And because it's open source, no being locked to AXS recorders for 4K RAW.

They have posted the first test images from the camera: https://www.apertus.org/axiom-alpha-first-images

It seems the camera will be offered at cost to beta testers.
