8K resolution would just fit in the 44.7MP:
Taking into account the 3:2 aspect ratio, it would make a camera of 8192x5460 pixels, allowing
- 2x2 pixel binning for 4K recording
- 4x4 pixel binning for fullHD recording
- full pixel use for 8K imaging
44.7MP sounds too great to be true!
IMHO the 44 MP will be a 22MP = because of the new focusing system. Remember 2 pixels instead of one?
Now that monster 75 MP - it most probably will be a 44 MP for real. Having that amazing focusing system.... now we are talking. I am looking forward for the ISO improvements though.
The Dual Pixel CMOS AF splits every single pixel into two photodiodes, so it looks to me it is a 44.7MP with 44.7x2x3 million photodiodes (x2 for dual pixel, x3 for 3 colors).
Looking at the 70D sensor of 20.2MP and taking into account the 1.6x crop factor, Canon could reach 51.7MP with the same tech as for the 70D.
So 44.7MP with Dual Pixel tech shall not be too complex to bring to the market in terms of sensor technology. This year for the C series and maybe next year for the rest of the line.
