Presumably this is why press photographers with their enormous kit seem to irritatingly flash anything indoors despite all this light bathing the sensor as the DOF is so impractically shallow that closing up the aperture is the only way they can ensure anything in focus. Rather defeats the purpose in my view.

The curious thing is that this means that if you stop-down the FF lens to give the same DOF as u4/3, and boost the ISO to maintain the same shutter speed, you end up an identical image in terms of DOF and image noise. This is what is meant by 'equivalence': there is no magical advantage to either FF systems if the cameras are correctly set so that the resulting images would be truly identical.
