A Thinner Sensor Stack
All sensors have glass in front of them, I'm aware of that.
That's not what I'm talking about.
I'm talking about a mechanism that would automatically protect the sensor itself so it would not be exposed when changing lenses.
It would prevent (or at least help prevent) dust from coming in and reaching the sensor.
Dust is obviously becoming more and more critical with high resolution sensors and keeping sensors clean of dust is not easy to achieve when often changing lenses in outdoor environments with potentially not clement weather.
