Very few, if any, of these small sensor cameras stop down less than f8 since the loss of sharpness due to diffraction is significant and the increase in DoF unnecessary. They didn't think of the type of thing you were trying to do, I suppose, or making such a small aperture accurate (f16 on a 5mm fl lens is 0.012") is not economically feasible. Frank D.
