Thanks Marie, yes they all have been shot with the same lens. For info, the adapter used for the Sony/Canon interface is a Sigma MC-11 (not sure about the firmware version though). I followed your advice for the tele-converter, all is fine with the TC 1.4x now.
I’ve opened a bug.
I’ll keep you updated.
To be honest, this is why I never bothered updating beyond PL3. I’ve got too many lenses that I can’t get profiles for.
