2. Setup and Assembly
The TCS20 camera is designed for quick and easy setup without the need for additional tools. Follow these steps for initial assembly:
- Attach the Focusing Rail: Secure the focusing rail to your tripod head using the five 1/4-inch screw holes for optimal balance. This rail can also function as a macro focusing rail.
- Mount the Camera Body Module: Connect the camera body bayonets mount to your Fuji GFX camera. Then, attach this assembly to the rear standard of the TCS20.
- Install the Lens Panel: Select the appropriate lens panel (e.g., Copal 0# or M39) for your lens and attach it to the front standard of the camera.
- Connect the Bellows: Ensure the bellows are securely attached between the front and rear standards, providing a light-tight connection.

3. Operating the Camera
The TCS20 offers precise control over various camera movements, essential for technical photography. All adjustments are made via knobs utilizing trapezoidal screws and worm gear mechanisms for enhanced accuracy.
3.1. Movements and Adjustments
- Pan: Adjust the horizontal angle of the front standard by up to ±20° using the dedicated pan knob.
- Tilt: Control the vertical angle of the front standard by up to ±15° using the tilt knob.
- Horizontal Shift: Shift the front standard horizontally by up to ±30mm.
- Vertical Shift: Shift the front standard vertically by up to ±25mm.
- Focusing: Utilize the micrometer scale on the focusing knob for precise focus adjustments along the Arca-Swiss compatible rail. A quick-moving crank is also available for rapid adjustments.

4. Maintenance
To ensure the longevity and optimal performance of your SWEBO TCS20 camera, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe down the camera body and components. Avoid abrasive cleaners or solvents.
- Bellows Care: Handle the bellows carefully to prevent punctures or tears. Store the camera in a way that avoids compressing or creasing the bellows unnecessarily.
- Lubrication: The precision screw and worm gear mechanisms are designed for smooth operation. Avoid applying external lubricants unless specifically instructed by SWEBO support.
- Storage: Store the camera in a clean, dry environment, away from extreme temperatures and humidity.
5. Troubleshooting
This section addresses common issues you might encounter with your TCS20 camera.
| Problem | Possible Cause | Solution |
|---|---|---|
| Difficulty with movements (pan/tilt/shift) | Knobs are too tight or debris in the mechanism. | Ensure knobs are not overtightened. Gently clean any visible debris. Do not force movements. |
| Light leaks | Bellows not properly attached or damaged. | Verify bellows are securely fastened to both standards. Inspect bellows for any tears or holes. |
| Camera not stable on tripod | Focusing rail not securely mounted or tripod inadequate. | Ensure all 1/4-inch screws are tightened. Use a sturdy tripod suitable for the camera's weight. |
