Summary
If the GX680 operates in two-shot mode it is because of a mismatch in exposure between control box and camera.
In-Depth
The wake-up and capture signals are generated and controlled entirely by the Kapture Group Control box. The exposure setting on the control box must match the exposure setting on the camera.
Here are the components to check:
- Cables
- Battery in the camera body (note that 2 batteries must be checked, internal and external).
- Check the battery in the ”One-Shot” controller box.
- Finally, test the back on a Hasselblad system.
