  1. You're making those assumptions based on traditional bayer-pattern sensor design. BMD's new sensor is a 6x6 array with a 2.2 micron pixel pitch (Alexa's pixel pitch is 8 microns for reference). This means an equal number of RGB pixels (similar to old 3X CCD designs, but on a single chip). We don't know enough about the impact this new design will have on performance other than what BMD has shown, and told us, but so far the implications are pretty revolutionary. The ability to have multiple native resolutions from a single sensor with 12k, 8k, and 4k not requiring any in-camera binning is insane. This means minimal to no aliasing, no moire, and incredibly efficient in-camera processing. Ultimately the 12K resolution wasn't the goal with this sensor, it was the by-product of the 6x6 array, and non-bayer design. It doesn't appear BMD set out to design a 12K sensor, they set out to create a new way to interpret light at the sensor level without a bayer pattern (hence their 3-chip CCD example in the video). BMD is finally playing with a "full deck" if you will. They have a custom sensor, with a custom codec BRAW, and their own suite of editing software, all vertically integrated. As long as they keep their innovative edge I'm excited to see how this new sensor technology evolves and what other limitations of traditional bayer-patterns it can overcome. You know you have a revolutionary product when the current models to predict dynamic range and other areas of performance don't apply, hence their "estimated" dynamic range claim...there isn't a third-party model that can independently verify that measure at this time.
