Mamiya C series TLR cameras coming into the repair shop go through several testing phases to determine working condition. After a visual inspection where I am looking for signs of impact, water or sand damage, a test roll is run through the camera to determine if the camera is working to specifications. Since the C series have two lens systems on the lens board, it is important to check that both lenses are tracking focus. This is done using a special Mamiya lens fixture and an autocollimator.
A report will be sent to the client regarding the state of the camera with estimate for needed repairs.
After repairs are made the camera goes through testing once more to ensure that it is as close to factory specifications as possible.
