4. Arahan Operasi
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. Keserasian
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.

Nota Penting
- 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. Penyelenggaraan
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.
