Introduction
Go to step 1 ↓The electronic speeds on the Super Program can be adjusted by connecting the shutter to the front block before it is reinstalled to into the camera. Curtain speeds should only be adjusted with a three sensor shutter tester that can accurately measure the travel times. The curtain delay can be adjusted to a reasonable degree with a single sensor tester.
