Herr Hektor vs Mr Davidons

Impressive colour rendition of an old Hektor 135 at f4.5 (maximum aperture) and my new A12 module, I think I've never had as good result with this lens as I've with A12 M GXR Ricoh, before the lens was used on a M4 and on my ex nex 5. I'm wondering about details richness and unusual (for this lens) sharpness, yes tehre is a trace of CA but is uncorrected (the shot is at "low iso" but I've noticed that there'is a narrow DR at this iso set):

Sorry for my bad English...
