Now, re IQ: you also need to compensate the f/number: divide the one you used for FX by 1.5. So, if you were using f/8, now you need f/5.6 (f/5.3 more precisely) for same DoF. That puts some limitations on DoF control, as expected from DX compared to FX

but this is good right.... as then for the same dof you can save one stop of light so less noise!!
