PS, You say "a larger sensor does allow you to use a lens with a larger entrance pupil and gather more light". From that I get a "foolish" thought. Might it (theoretically?) be possible to build a low light camera using big entrant lenses collecting much light and have all this light focused on a minimal 1/2.3 sensor?? In a way like an astronomical telescope.

To replicate my 50/1.2 on FF, you would need something like an 8.9/0.21 lens, which would be faster than the theoretical limit of f/0.5, not to mention the practical one f/1 or so.
