Introduction
The Vivitar VIV-EXT-N Extension Tube Set is designed for close-up photography with Nikon F SLR cameras. This set allows you to move your lens farther from the camera's image plane, enabling greater magnification for macro photography. It is ideal for capturing detailed images of small subjects.
Product Overview
Image: The Vivitar VIV-EXT-N Extension Tube Set, showing the three different sized tubes (12mm, 20mm, 36mm) and a lens cap. These tubes are designed to be mounted between a camera body and a lens to increase magnification for macro photography.
The Vivitar VIV-EXT-N set includes three extension tubes of varying lengths:
- 12mm Extension Tube: Provides a moderate increase in magnification.
- 20mm Extension Tube: Offers greater magnification than the 12mm tube.
- 36mm Extension Tube: Delivers the highest magnification among the three tubes.
These tubes can be used individually or combined to achieve different levels of magnification. They are designed for use with Nikon F SLR cameras.
Setup and Installation
Follow these steps to properly attach the Vivitar extension tubes to your camera and lens:
- Prepare Equipment: Ensure your camera and lens are clean and free of dust.
- Select Tube(s): Choose the desired extension tube(s) based on the magnification needed. You can combine multiple tubes by attaching them to each other.
- Attach to Lens: Align the red dot or index mark on the extension tube with the corresponding mark on your lens. Gently twist the tube clockwise until it clicks into place. Ensure a secure fit.
- Attach to Camera Body: Align the red dot or index mark on the assembled extension tube (or single tube) with the corresponding mark on your Nikon F SLR camera body. Gently twist the assembly clockwise until it clicks into place.
- Verify Connection: Lightly tug on the lens/tube assembly to ensure it is securely mounted and does not wobble.
Important Note: The fit of extension tubes can sometimes be tight. Exercise care and precision when attaching and detaching to avoid damage to your camera or lens. If a tube feels stuck, ensure the release pin is fully depressed. Avoid forcing the connection.
Operating Instructions
Using extension tubes for macro photography requires specific considerations:
- Manual Focus: When using extension tubes, autofocus functionality is typically lost. You will need to manually focus your lens to achieve sharp images.
- Light Requirements: Extension tubes increase the distance between the lens and the sensor, which can lead to a significant loss of light. You may need to compensate by:
- Increasing ISO sensitivity.
- Using a wider aperture (smaller f-number).
- Employing external lighting, such as a flash or continuous light source.
- Depth of Field: Macro photography with extension tubes results in a very shallow depth of field. Precise focusing is crucial.
- Stability: Due to the high magnification and shallow depth of field, even slight camera movement can cause blur. It is highly recommended to use a tripod or other stable support system for best results.
- Working Distance: The working distance (distance between the front of your lens and the subject) will become very short.
Maintenance
Proper care will extend the life of your Vivitar extension tubes:
- Cleaning: Use a soft, lint-free cloth to wipe the exterior of the tubes. Avoid using harsh chemicals. For dust on the internal surfaces, use a blower brush. Do not touch the internal electrical contacts (if present) with your fingers.
- Storage: Store the tubes in a dry, dust-free environment, preferably in a protective pouch or case when not in use.
- Handling: Always handle the tubes by their barrel, avoiding contact with the mounting surfaces or internal components.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Extension tube stuck on camera/lens. | Release pin not fully depressed; tight fit. | Ensure the release button/pin is fully pressed. Gently wiggle the tube while pressing the release. Do not force. If necessary, use a thin, non-abrasive tool to gently assist the release pin if it's not retracting fully. |
| Camera displays "no lens attached" or similar error. | Improper mounting; dirty electrical contacts (if applicable). | Re-attach the tube and lens, ensuring they click securely into place. Clean the electrical contacts on both the tube and camera/lens with a clean, dry microfiber cloth. |
| Images are dark or underexposed. | Light loss due to increased lens-sensor distance. | Increase ISO, use a wider aperture, or add external lighting (flash, continuous light). |
| Images are blurry or out of focus. | Manual focus required; camera shake; shallow depth of field. | Carefully adjust manual focus. Use a tripod or stable surface. Consider focus stacking techniques for increased depth of field. |
