You are thinking it totally wrong way!

No, in fact you are.

A 1mm on reality is 1mm on sensor!

Which means exactly nothing, because you are not watching your photos on a sensor. You are watching photos on a screen or paper, which has the same size, regardles of what sensor was used to capture the photo.

It would make sense to say 1mm in nature is xxx pixels on sensor. That way proper and direct comparison between differently sized sensors could be made. And it that case 1 mm is 100 pixels on sensor would mean the same, regardles of the sensor size. But alas, nobody is measuring macro capabilities in such a way.

Again, you are saying that a 50mm lens is a 50mm lens, regardles of what sensor is used. Which is technically true, but it means nothing without knowing what sensor is used. Because of that we are all talking in equivalent focal lenghts (with a 35mm sensor choosen as a standard).

1:1 macro means nothing, if you don't know what sensor is used. And saying that 1:1 on a m4/3 system is the same as 1:1 on a full frame system is wrong, plain and simple.

Below are two photos, simulating 1:1 on a full frame and an m4/3 camera. It is very appropriate to say that 1:1 on a m4/3 is equivalent to a 2:1 on a full frame.

1:1 with a full frame camera

1:1 with a m4/3 camera
