A year ago, I loaded up my Contaflex IV, took a few shots, and then forgot about the roll until recently. I finished it, but the results show the effect of a warm room on year-old film. Still, some of the interesting feel of the Tessar lens comes through, as well as some of its sharpness. I think the ceiling shot is the purest Tessar look. The sharpness came through for the last shot. Thank Goodness.
