1. Pengenalan
The VILTROX DG-C Auto-Focusing Macro Lens Extension Tube set is designed to transform your existing Canon EF/EF-S series lenses into macro lenses. These tubes allow for closer focusing distances, enabling macro photography without requiring a dedicated macro lens. The set includes three tubes of different lengths (12mm, 20mm, and 36mm) that can be used individually or combined to achieve various magnification levels.
The extension tubes maintain electronic communication between your camera and lens, supporting auto-focus and exposure control. They feature metal bayonets with surface plating for durability and gold-plated pins for stable signal transmission.

Follow these steps to attach the extension tubes to your camera and lens:
- Attach Tube to Camera: Align the red dot on the extension tube (or the first tube if combining multiple) with the red dot on your camera body. Rotate the tube clockwise until it clicks into place, indicating a secure connection.
- Attach Lens to Tube: Align the red dot on your lens with the red dot on the front of the attached extension tube. Rotate the lens clockwise until it clicks into place.
- Combining Multiple Tubes (Optional): If using multiple tubes, attach them to each other in the desired order (e.g., 12mm, then 20mm, then 36mm) before attaching the entire assembly to the camera and then the lens. Ensure each connection clicks securely.

5.1 Tube Combinations
The three tubes (12mm, 20mm, 36mm) can be used individually or combined to achieve seven different lengths and magnification ratios:
- 12mm
- 20mm
- 36mm
- 12mm + 20mm (32mm total)
- 12mm + 36mm (48mm total)
- 20mm + 36mm (56mm total)
- 12mm + 20mm + 36mm (68mm total)
5.2 Focusing Recommendations
When using extension tubes, the focusing distance of your lens changes significantly. Please note the following:
- Autofokus: Auto-focus functionality is generally maintained with a single extension tube. However, when combining two or three tubes, auto-focus may become less reliable or difficult to achieve.
- Fokus Manual: For optimal results and precise focusing, especially when using multiple tubes or with focal lengths less than 70mm, it is recommended to switch your camera to manual focus (MF) mode.
- Focal Length Consideration: If your lens's focal length is less than 70mm, it is generally not recommended to combine two or three rings simultaneously, as this can make focusing challenging.

6. Penyelenggaraan
To ensure the longevity and optimal performance of your VILTROX DG-C extension tubes, follow these maintenance guidelines:
- Pembersihan: Use a soft, dry, lint-free cloth to clean the exterior of the tubes. For the electronic contacts, use a clean, dry cotton swab. Avoid using harsh chemicals or abrasive materials.
- Storan: Store the extension tubes in a dry, dust-free environment, preferably in their original packaging or a protective pouch, when not in use. Ensure the front and rear caps are attached to prevent dust and debris from entering.
- Pengendalian: Handle the tubes carefully to avoid dropping them or subjecting them to impact, which could damage the internal electronics or mechanical components.
- Kelembapan: Keep the tubes away from water and high humidity. If they become wet, dry them immediately with a soft cloth.
7. Penyelesaian masalah
If you encounter issues while using your VILTROX DG-C extension tubes, consider the following:
- No Auto-Focus or Exposure Control:
- Ensure all connections (camera to tube, tube to tube, tube to lens) are securely clicked into place.
- Check the gold-plated electronic contacts on both the tubes and your lens/camera for dirt or damage. Clean them gently if necessary.
- If using multiple tubes, try using a single tube to see if auto-focus functions. Auto-focus performance can decrease with increased extension.
- Verify your camera and lens are compatible with the DG-C tubes.
- Kesukaran Memberi Fokus:
- Macro photography requires very precise focusing. Switch to manual focus mode for better control.
- Consider using a tripod to stabilize your camera setup.
- If using multiple tubes, the working distance (distance between the front of the lens and the subject) becomes very short. Adjust your distance to the subject carefully.
- Sambungan longgar:
- Ensure the tubes are rotated clockwise until they firmly click into place.
- Inspect the bayonet mounts for any physical damage or debris that might prevent a secure fit.
