Ok, because of the crop factor, you'll be standing in approximately the same
position with a 200mm on a FF camera as you would with a 100mm on a 4/3 camera
to fill the respective frame with the same subject. Effectively you have the
same working distance but a different magnification (e.g. 1:1 on FF, 1:2 on
4/3).
