>>3303222The D5 use old Front side illuminated CMOS manufacturing from the 2012-era.
In addition, it's metal interconnects between each pixel need to be wider than normal, in order to facilitate the higher than normal data transfer (high frame rate).
The end result is you get a clusterfuck sensor that has good frame rates, but has similar low light sensitivity compared to the average 24MP camera from 2012~2014.
And similar pixel size as those 24MP sensors.
Nothing in life is free when you use inferior semiconductor manufacturing technology. You need to compromise.
