This lens (the Nikkor, to be precise, and here the AI version to be even more precise) is full of surprizes. The shot below was just experimental, with no "intention" except than checking sharpness, bokeh, reaction to strong light etc.
Nearly no PP (not even distortion correction). It was shot wide open, and the original vignetting was kept "as is". I originally posted it on FB to amuse others (I was on a biz trip in Brussels), but reactions were quite positive, so here it is.
Note : my AIS copy, though at least as sharp, displays more vignetting. Did you also observe that ?
