I found this lens at a shop in Paris (rue de Suffren), already adapted to the F mount, which means: no electric contacts, not even a link to the diaphragm, manual closure of said diaph and stopped down metering after having focussed wide open.
The lens has lots of qualities - good color (very slightly cold), very good IQ wide open, little LoCA, very little bokeh outlining, low distortion, acceptable vignetting, good performance at short range too. Short, the pictures look natural and detailed. I feel the breeze circulating in there, so to say.
Only the coatings show their "age" - the lens flares more than recent ones would. As I use to say, it is a good lens for overcast days and will bring grayish scenes to life.
A few samples from these last few days :
