Stumbled along this whilst researching the possible Blackmagic Production Camera 4K CMOS sensor from CMOSIS.

 

They really do have something pretty special here... And maybe a sign of things to come in DSLRs. Nearly double the pixel count of the Nikon D800.

 

It is 35mm full frame.

The CHR70M is a high resolution CMOS image sensor with 10000 by 7096 pixels. The image array consists of 3.1μm x 3.1μm pinned diode pixels which share a number of transistors (2 pixels sharing). The image sensor has 8 analog outputs, each running at 30MHz. This results in a frame rate of 3fps at full resolution. Higher frame rates can be achieved in windowing mode or subsampling mode.

The image sensor also integrates a programmable gain amplifier and offset regulation. These and other settings are all programmable using the SPI interface. All internal exposure and read out timings are generated by a programmable on-board sequencer. External triggering and exposure programming is also possible.

The CHR70M is derived from a custom CMOS image sensor
