43rumors leaked the images and specs of the new OM-1 Micro Four Thirds camera that will be announced on Feb 15. the interesting bit for use is that it uses the new 20mp IMX472 Quad Pixel sensor from Sony (You can download the PDF here).
If I got it right the OM-1 will have a high dynamic range mode that allows to combine 4 pixels in 1 and create a 20Mp image with 2 stops of dynamic range gain.
