Another way to illustrate this:

Same aperture.

So, lets take again equivalent focal lengths (similar field of view) for FF and 4/3rds (easy to calculate due to 2x crop factor) as example.

100mm on FF, 50mm on 4/3rds. Both f2.

100mm / 2 = 50mm opening. 50 / 2 = 25mm opening.

The FF sensor can gather much more light per pixel, simply because the opening is 4x bigger. Then how come the exposure times are similar???

Because ISO is not ISO anymore. Not about sensitivity. For the 4/3rds sensor to reach that "ISO 100" level, the signal is amplified more than that of the FF sensor.

To get a similar total amplification. just use EQUIVALENT ISO settings.

To get a similar field of view, just use equivalent focal lengths.

To get a similar depth of field, just use equivalent f-values.
