Exposure value also must be converted between sensor sizes too

To get the same depth of field at the equivalent angle of view, you would need an aperture two stops bigger. With that said, the exposure value would be the same. In other words, if f/2.8 would give you 1/60s on a 135 camera then it will give you 1/60s on a m4/3 camera.

You can't compare equal ISO's between the systems. FF has 4x the dynamic range, so you would need to set ISO to 4x as high. Ie., ISO100 on m43 is ISO400 on FF.
