The lens being an AI-P, focus assistance works fine, including donkey eye detection. A perfect pairing of a gorgeous lens with a gorgeous camera. Only missing an inspired photographer here - I was on a walk at dusk with Madame, so lacked time to "stand and stare".
As usual (with me), the files were very lightly retouched : some raising of shadows, some moderate cropping, that's all. Auto WB, colors were left alone.
