Conditions were heavy overcast so probably EV 12. The print exposed normally in the darkroom so I know the negative was correctly exposed (looks it, too). Based on depth of focus, my guess is 1/1000 with the lens set at f/2.0. *Maybe* 1/2000 with the lens wide open, but I don't think the DOF has the look of the f/1.4 setting.
Thanks for the question...good deductive reasoning practice as vacation winds down .
