The RED Helium 8K (approx. APS-H size sensor) just leapt to the top of the DXOMark charts with a score of 108.
Panasonic froze image sensor research and development in 2011 and have only now resumed.
The company has committed $80m to revitalise their image sensors business in light of growing revenue from their imaging business as a whole and hot demand for sensors.
One of the goals of the $80m investment is the creation of an 8K sensor to be released in Panasonic cameras around 2018.
This is a fantastic Sony interview at Imaging Resource, where Dave Etchells was able to extract a huge amount of technical info about how the new Sony sensors are able to deliver 4K video from 42MP. On top of that there’s less rolling shutter and better low light performance than the previous 36MP full frame and 20MP 1″ sensors.
I have some information on a new 4K CMOS sensor which may or may not be announced at NAB in a future Blackmagic camera.
