I got this lens a while ago in very rough condition (scratch on the front element) for an irresistibly attractive price. Today I finally took it out for a walk. Recently in (there was a url link here which no longer exists) I read that the bokeh is not very good, and saw at least one example that was definitely nasty.
So today I shot everything in duplicate at f/1.9 and f/2.8, thinking a bit of stopping down might help. To my relief the results looked reasonably good at either aperture. The samples shown below were all f/1.9
On this last one something obviously went wrong in the developing process. Almost looks like something was stuck to the negative but I didn't notice anything. Can anyone help me figure out what happened?
