[QUOTE="J-see, post: 403129, member: 31330"] From what I read ISO control has a lot to do with the sensor pixel size and when going through the list of all cams released during the years, I do notice an increase in Mpix but I also notice those pix getting smaller. The D810 got more but they're slightly smaller than those of the D750 which could explain the difference in noise handling. Canon seems to prefer the "less but bigger" approach. The DF and D4S have both some impressive sized pixels but sacrifice resolution for that. I think they can easily add everything else to a newer cam but better ISO handling will be harder. I really makes me wonder if the D5500 pixel size is a typo and should be 3.9 like those of today. They can only change the sensor area when they want to change the pixel dimensions. Which means they'll not be changing the sensor. The D750's sensor is 35.9mm and if you divide that by the 6016 resolution, you roughly get the 5.9 micron each sensor pixel is. D610 and D750 are both 5.9 so at that level there's no difference between sensors and SNR. That also means that if the 48Mpix cams they talk about will have the same sensor area, they'll have to shrink the sensor pixels to some 4.5 micron which isn't a good thing. If they then want less noise, they have to start cheating. [/QUOTE]
