BMD could do a $500 pocket 6k, using the Light sensor modules and processing, which Sony are making for them. Somebody is bound to do something, then BM would have to compete.
You pull a cinema lens image on something a little bigger in top area then a larger sensor, no more add on lens, in a mobile phone lime size, which means you can rig it in a cage case for extra battery, lights, microphone, and still be smaller than a pocket 4k. No need to watch the focus pull, it can be done in post to imitate a variety of famous cine lenses, and as far as reframing, using 4k images from multiple sensors they could calculate more than 8k images apparently, and you might talk about 20 stops re-exposure latitude. So, a 6k pocket might be beyond 12k calculable images.
. I wonder how good though, and if you could calculate out descent 8k images from 2k sensor arrays.
