There is no increase in range. There is a smaller image area; one can
get the same "range" by cropping.

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


Not really. If you use a high resolution camera with good glass, you have the
same "range" as well as a wider area and more control over depth of field.


Not yet. Even the 61MP Sony only has 15MP if you crop it to m4/3
size. And most FF cameras top out at 45-48 MP, giving you 11-12
MP if cropped.


there's no reason to crop and it voids and comparison.

Regarding DOF, at those extreme tele ranges the more DOF you
have, the better.


not necessarily.

sometimes shallow dof is desirable.
