One thing that sprang to my mind when reading this:
- so camera sets aperture, say f/1.2, and ISO, say 100
- camera reads exposuring info from metering sensor and sets speed, say 1/250s.
- camera says to itself "f/1.2 will make my photo darker than it should be (ie, more than 2 stops darker than f/2.4), so i

If it were truly "useless" in the sense that the light from marginal rays at f-numbers faster than f/2 are lost at the sensor, you wouldn
