There is no increase in range. There is a smaller image area; one can get

This myth of "extra reach" has gone on for far too long.

But you have to heavily crop with a FF sensor, while with the
m4/3 camera the complete sensor is used for the image capture.

all cameras use 'the complete sensor'.

So - if you use the full sensor also in the FF case - m4/3
offers a doubling of range.

no it doesn't.
