>>3984194Ok, again I humbly put forward I am not an expert on this whatsoever. I am assuming that the more pixels that have to be created for each millimeter square of physical sensor, the more noise will be generated based on things I've read on this topic.
Therefore, if we hold the same sensor technology, we could work out a resolution in megapixels that a M4/3 would need to have to generate the same amount of noise as a full frame sensor.
Full Frame: 36 x 24 mm = 864 mm^2
Micro Four Thirds: 17.3 x 13 mm = 224.9 mm^2
That is 384% more surface area on the sensor.
24 Megapixel on FF = 6.25 MP Micro Four Thirds
Thus, if Olympus or Panasonic used the same sensor as a Sony a7iii, they would need a 6.25MP pixel resolution.
That's my theory anyway. Hope that helps.
