Sorry, I meant LSO = Lens Sharpness Optimization. In PL8 LSO Intensity has values in the [-3,3] range, while in PL9 it’s [0,200]. The corresponding parameter in DOP files for both PL versions is called ‘BlurIntensity’ (sic!).
See also Lens Sharpness Optimization V2 question - #3 by Wlodek for the mapping.
