Viltrox DG-C Auto Focus Macro Extension Tube Set for Canon EF/EF-S Lenses User Manual

1. Introduction

This manual provides comprehensive instructions for the Viltrox DG-C Auto Focus Macro Extension Tube Set. This set is designed to transform your standard Canon EF/EF-S lenses into macro lenses, allowing for close-up photography with increased magnification. The extension tubes are placed between your camera body and lens, moving the lens further from the sensor to achieve closer focusing distances without altering the optical quality, as they contain no optical elements. This set supports auto-focus functionality and automatic diaphragm coupling with TTL and AE type cameras.

3. Setup

Attaching the Extension Tubes

To attach the Viltrox DG-C Macro Extension Tube Set to your camera and lens, follow these steps:

1. Align the red dot on the desired extension tube (or the first tube in a combination) with the red dot on your camera body. Gently rotate clockwise until it locks into place with an audible click.
2. If using multiple tubes, align the red dot on the next extension tube with the red dot on the previously attached tube. Rotate clockwise until it locks. Repeat for additional tubes.
3. Align the red dot on your lens with the red dot on the last attached extension tube. Rotate clockwise until the lens locks into place.

Ensure all connections are secure before use. To detach, press the lens release button on the camera body (or the tube release button on the extension tube) and rotate counter-clockwise.

4. Operating Instructions

Understanding Extension Tubes

Extension tubes increase the distance between your lens and the camera's sensor. This reduces the minimum focusing distance of the lens, allowing you to focus much closer to your subject and achieve higher magnification ratios for macro photography. Since there are no optical elements, the image quality of your lens is preserved.

Using Individual and Combined Tubes

The Viltrox DG-C set includes 12mm, 20mm, and 36mm tubes. These can be used individually or combined to achieve different levels of magnification. There are seven possible combinations:

• 12mm tube only
• 20mm tube only
• 36mm tube only
• 12mm + 20mm tubes
• 12mm + 36mm tubes
• 20mm + 36mm tubes
• 12mm + 20mm + 36mm tubes

Experiment with different combinations to find the ideal magnification for your subject.

Auto Focus and Manual Focus

The Viltrox DG-C extension tubes support auto-focus (AF) functionality, allowing your camera and lens to communicate electronically. However, when using all three rings together, auto-focus can become challenging due to the extremely shallow depth of field at high magnifications. In such cases, it is recommended to use manual focus for precise control. Alternatively, increasing the lens focal length can sometimes assist with AF performance when multiple tubes are combined.

5. Maintenance

To ensure the longevity and optimal performance of your Viltrox DG-C Macro 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 cleaning solution. Avoid touching the contacts with your fingers.
• Storage: Store the extension tubes in a dry, dust-free environment, preferably in their original packaging or a protective pouch. Keep them away from extreme temperatures and humidity.
• Handling: Always handle the tubes by their barrel, avoiding pressure on the electronic contacts or bayonet mounts.

6. Troubleshooting

If you encounter issues while using your Viltrox DG-C Macro Extension Tube Set, consider the following:

• No Auto Focus or Electronic Communication:
  • Ensure all tubes and the lens are securely attached and locked into place.
  • Check that the electronic contacts on both the tubes and your camera/lens are clean and free from dust or debris.
  • If using all three tubes, try using fewer tubes or switch to manual focus, as AF can be difficult at very high magnifications.
  • Verify compatibility with your specific camera and lens models.
• Difficulty Focusing:
  • Macro photography inherently has a very shallow depth of field. Small movements can significantly change focus.
  • Consider using a tripod for stability and fine-tuning focus by moving the camera slightly forward or backward.
  • Utilize your camera's live view and focus peaking features for more precise manual focusing.
• Loose Connections:
  • Ensure each tube and the lens are rotated clockwise until they click firmly into place.
  • Avoid excessive force during attachment to prevent damage to the mounts.
