Embarassment/Learning Time or Confession is Good for the Soul Time
All is well. There never was a problem except for me not knowing how the GX 680 really works.... here's the deal. Turns out when one hits the mirror up switch it also closes down the lens as one might suspect and keeps it that way so as not to expose film. Until one wants to expose the film. Thinking about that will make it quite clear. epig's note about the mirror up switch did the trick. And it did the job, Sir, and I thank you. Turns out the same switch on the "bad" body was up when it was tried and it may not be a "bad" body at all. Tomorrow's test will reveal that for us. It, too, was 'up' when tried yesterday. Sloppy work on my part. My father would not be pleased with such work, but might be pleased by figuring this all out. Thanks for all considerations.
