Meike inform me that a firmware update to this lens is no available which should improve performance. Here we have a VERY affordable, full-frame, 85mm f/1.4 for Nikon Z and Sony E cameras - let's put it through its paces. Meike have informed me that the current production version of this lens could be somewhat improved. I've asked them to explain further but they're not replying to my emails any more (!).
