late winter afternoon finally got a chance to open the Industar up to almost full aperture
some seriously vintage bokeh happening (as the lens is 40 years old (give or take) no surprise there) also I think the lens + the Zorki 4 it was on are not co-calibrated... once I get the Zorki1 fully fixed it will go back on there.
