It doesn't have the usual PF/CA that I would have expected, actually as you can see they are totally absent even around the blownout lights. This is mighty impressive.
However, a few interior shots with a wide dynamic range, like a bright window to one edge does cast a light leak look in a few shots.
I've sharpened these shots, definitely soft at f2.
