This lens draw beautiful, but has some serious CA.

Not really a problem for the prevalent B&W film of the day. Besides, the CA is only really in the bokeh and the first image seems to be shot wide open.

Beautiful! Especially #2. In #1 the girl looks a little bored and fed up, but I like the processing. Smile
