>>3552534>>An Olympus f/1.4 lens has the total light gathering of a FF f/2.8 lens.>Red herring. You don't apply the crop factor for exposure. You basically can. A FF sensor will yield nearly the same noise as a mft one at 2ev less exposure. (The actual difference is closer to 1 2/3ev, so at -2ev FF noise will be slightly worse.)
