4. Operating Instructions
Focal Length Extension
The TC-2.0X Teleconverter doubles the focal length of the attached lens. For example, a 70-200mm lens will effectively become a 140-400mm lens when used with this teleconverter. This allows for greater magnification of distant subjects.

Autofocus Functionality
The VILTROX TC-2.0X Teleconverter is designed to maintain the autofocus capabilities of the attached lens. While autofocus accuracy and speed are largely preserved, minor variations may occur depending on lighting conditions and the specific lens used.

EXIF Information Transmission
The teleconverter supports the transmission of EXIF data between the lens and the camera body. This ensures that focal length, aperture, and other relevant shooting information are correctly recorded in your image files.
5. Compatibility
The VILTROX TC-2.0X Teleconverter is compatible with specific Sony E-mount lenses and the Viltrox 135mm F1.8 LAB FE lens. Refer to the compatibility list below. When a teleconverter is installed, the lens aperture value will be doubled (e.g., f/2.8 becomes f/5.6). Simultaneously, with reduced light intake and enhanced diffraction, image quality may suffer from decreased resolution and increased vignetting at extreme apertures. Therefore, when using a teleconverter, the lens will block both large and small apertures; select a mid-range aperture for optimal image quality.

Important Notes
- Stacking of adapter rings (including Viltrox E-Z adapter ring) is not supported.
- Lenses not on the compatibility list are not supported; using them may damage the lens or camera.
- When using a teleconverter, the camera must be turned off before disassembling and installing it.
6. Maintenance
The VILTROX TC-2.0X Teleconverter features a dustproof and anti-drip design to protect its internal components from environmental elements. To ensure longevity and optimal performance:
- Keep the lens surfaces clean using a soft, lint-free cloth and lens cleaning solution.
- Avoid touching the electrical contacts on either side of the teleconverter. If necessary, clean them gently with a dry, clean cloth.
- Store the teleconverter with its front and rear caps attached in a dry, cool place when not in use.
- Avoid exposing the teleconverter to extreme temperatures or humidity.

7. Troubleshooting
If you encounter issues with your VILTROX TC-2.0X Teleconverter, consider the following:
- Autofocus Issues: Ensure the teleconverter and lens are securely mounted. Check for clean electrical contacts. Autofocus performance may be reduced in very low light or with subjects lacking contrast.
- Image Quality Concerns: Verify that your lens is on the compatibility list. As noted, using a teleconverter can affect image quality, especially at wide-open or very narrow apertures. Try shooting at a mid-range aperture.
- Camera Not Recognizing Lens: Power off the camera, detach and reattach the teleconverter and lens, ensuring secure connections and clean contacts.
- Firmware Update: The teleconverter features a USB-C firmware upgrade interface. Check the VILTROX official website for the latest firmware updates and instructions if you experience compatibility or performance issues.
