It wasn’t all that long ago that we were being told that this is only useful for small sensors. What’s changed?
Video has changed it (faster readout speed due to a better ground plane, as has the ability to put more complex circuitry on the sensor. Multi layer sensors as in the Sony A9 are the next step as far as faster sensor readout, but very expensive. Photosites on sensors are about as good as they can get as far as low light, some sort of tech breakthru would be needed to have a big boost, so small gains from BSI are now the best low cost way to improve. We see lots of claims of new tech, but most of them are really just fishing expeditions looking for more R&D money.
