sorry to be a pain but surely a 12-24 Nikon DX lens does not correspond to 24-48mm on full frame since the crop factor from DX to FX is 1.5x...hence 18-36mm on FX

You are not a pain at all, many people are confused in these matters, you are not alone, and I'm willing to help to explain. As also others have stated, a 12-24 mm lens on a m43 is still a 12-24 mm lens, and with the 2x crop factor it corresponds to 24-48 on a FF. But if you on the other hand put this 12-24 on an APS-C Nikon with crop factor of 1,5x it corresponds to 18-36 on an FF.
