CMos Sony imx078cqk : Exmor R tech' = on chip column-parallel A/D Convertion. R = backside illuminated : IMO the GQE (green efficiency) should be ~75% ! that was just incredible a few years ago for a Bayer Filtered sensor ! 75% is current QE for Unfiltered Astro imaging CCD sensors. The ratio between the DxoMark Low-Light ISO score and Sensor Area versus Canon APSc : - Eos 60d, 60d-Astro, 600d = ISO ~800 for ~15 x 22.5 mm = 2.37 ISO / mm² - Pentax Q, Q10 = ISO ~186 / 4.6 x 6.15mm = 6.57 ISO / mm²
