1. Introduction
The Viltrox DG-C Auto Focus Lens AF Adapter Macro Extension Tube set is designed to transform your standard lens into a macro lens, enabling close-up photography with greater magnification. This set is compatible with Canon EOS EF/EF-S SLR cameras and lenses.
The extension tubes are placed between the camera body and the lens, increasing the distance between the lens and the film or digital sensor. This increased distance allows for closer focusing and higher magnification without affecting the optical quality of the image, as there are no optical elements inside the tubes. Unlike close-up filters, which can degrade image quality, these extension tubes maintain the original lens's performance.
The DG-C extension tube set supports the camera's automatic diaphragm, TTL (Through-the-lens) metering, and AE (Automatic Exposure) modes, ensuring seamless integration with your camera's functions.
2. Package Contents
Please check the package for the following items:
- 1 x DG-C Extension Tube Set (12mm, 20mm, 36mm tubes)
- 1 x English user manual
- 1 x Front Cap
- 1 x Rear Cap
3. Setup and Installation
The Viltrox DG-C extension tubes are designed for easy and secure attachment between your Canon EOS camera body and EF/EF-S mount lens. Follow these steps for proper installation:
- Attach the Adapter Ring to the Camera Body: Align the red dot on the adapter ring (the tube you wish to use first) with the red dot on your camera body.
- Secure the Adapter Ring: Rotate the adapter ring clockwise until it clicks into place, indicating a secure installation.
- Attach the Lens to the Adapter Ring: Align the red dot on your lens with the red dot on the installed adapter ring.
- Secure the Lens: Rotate the lens clockwise until it clicks into place, ensuring a firm connection.
The tubes can be used individually or in various combinations (12mm, 20mm, 36mm, 12+20mm, 12+36mm, 20+36mm, 12+20+36mm) to achieve different magnification levels. Note that using all three tubes together might not always be practical or recommended depending on the lens and desired effect.
4. Operating Instructions
Once installed, the Viltrox DG-C extension tube set allows you to explore the world of macro photography. The tubes maintain auto-focus functionality and adjustable aperture with compatible lenses, ensuring ease of use.
The set includes 12mm, 20mm, and 36mm tubes. These can be used individually or combined to achieve 7 different lengths, providing flexibility for various macro photography needs. Experiment with different combinations to find the optimal focusing distance and magnification for your subject.
The extension tubes are designed to work with your camera's automatic systems, including TTL metering and AE modes, for consistent exposure. This allows you to focus on composition and capturing intricate details.

5. Maintenance
To ensure the longevity and optimal performance of your Viltrox DG-C extension tube set, follow these maintenance guidelines:
- Cleaning: Use a soft, lint-free cloth to gently wipe the exterior of the tubes. For the electronic contacts, use a clean, dry cotton swab or a specialized contact cleaner if necessary. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the extension tubes in a dry, dust-free environment when not in use. Use the provided front and rear caps to protect the mounts from dust and scratches.
- Handling: Handle the tubes with care to prevent drops or impacts, which could damage the precision components.
The tubes are constructed from aviation aluminum, integrated by CNC machine tools, providing strong and wear-resistant performance. The pure copper contacts feature a gold plating process to ensure stable power supply and information transmission between the lens and camera. The threaded matt sidewall treatment helps prevent internal reflections that could affect image quality.
6. Troubleshooting
- Auto-focus not working: Ensure that the extension tubes and lens are securely mounted to the camera body. Check that the electronic contacts on both the tubes and the lens are clean and free from obstruction. The auto-focus function operates with compatible AF lenses; it does not convert a manual focus lens into an auto-focus lens.
- Cannot use all three tubes together: While the tubes can be combined, some users have noted that using all three (12mm + 20mm + 36mm) simultaneously might not always be stable or provide the desired results with all lens types. Experiment with fewer combinations if you encounter issues.
- Image quality issues: Ensure all connections are tight and there is no light leakage. Clean the lens and camera sensor if smudges or dust are suspected.
