Depends on how you interprete it, since the FOV of 100mm lens in 35mm system
is equal to 50mm lens in 4/3 system. That means for the same object you
will need the same working distance for both. If you are satisfy with
working distance of 100mm macro lens in 35mm system it will be the same for
50mm lens in 4/3 system, that is simple math.
