Field curvature can mathematically be described (really, is) in terms of mm of defocus at the image plane.  The issue is that this is scaled by the focal length.  There is no way to model the field curvature in terms of the object distance in a way which is independent to FL.  Short FLs will also obfuscate that with large DoF.
