- Rotate the teleconverter clockwise until you hear a distinct "CLICK" sound, indicating it is securely locked onto the lens.
5.2. Attaching the Lens and Teleconverter Assembly to a Camera
- Align the red circle mark on the teleconverter (now attached to the lens) with the red circle mark on your Canon EOS SLR camera's lens mount.
- Rotate the entire assembly (lens + teleconverter) counter-clockwise until you hear a "CLICK" sound, confirming it is securely attached to the camera.
5.3. هٽائڻ
To remove the teleconverter, reverse the installation steps. First, detach the lens and teleconverter assembly from the camera, then detach the teleconverter from the lens.
6. آپريٽنگ هدايتون
Once installed, the VILTROX C-AF 2X II Teleplus operates seamlessly with your camera and lens. The primary function is to extend the focal length, effectively doubling it. For example, a 70-200mm lens will become a 140-400mm lens when the teleconverter is attached.
- خودڪار فوٽو: The teleconverter supports the autofocus function of your lens. However, autofocus speed may be affected, especially in low light or with certain lens combinations.
- پڌرائي: The teleconverter will reduce the effective aperture by approximately 2 stops (e.g., an f/2.8 lens becomes an f/5.6 lens). The camera's exposure system will automatically compensate for this change.
- ميدان جي کوٽائي: The depth of field will be approximately half of the original lens at the same effective aperture.

9. مسئلا حل ڪرڻ
If you encounter issues while using your VILTROX C-AF 2X II Teleplus, refer to the following common problems and solutions:
| مسئلو | ممڪن سبب / حل |
|---|---|
| Slow Autofocus | Teleconverters can inherently slow down autofocus speed, especially in low light or with lenses that have smaller maximum apertures. Ensure sufficient light and contrast in your subject. Some lenses may perform better than others. |
| Autofocus Issues at High Zoom | Some lens and teleconverter combinations may struggle with autofocus accuracy or speed when the lens is zoomed to its maximum focal length. Try focusing at a slightly wider focal length or using manual focus if necessary. |
| Diminished Image Quality | Teleconverters can sometimes introduce a slight reduction in image sharpness or contrast, particularly at the edges of the frame or when shooting wide open. This is a common characteristic of optical extenders. Ensure the lens and teleconverter are clean and properly mounted. Using a slightly smaller aperture (e.g., f/8) can sometimes improve sharpness. |
| Teleconverter Not Recognized by Camera | Ensure the teleconverter is securely mounted to both the lens and the camera, with a distinct "CLICK" sound at each connection. Check that the electronic contacts on both the teleconverter and the lens/camera are clean and free of debris. Try cleaning the contacts with a clean, dry cloth. |
| Incompatible Lens/Camera | Verify that your lens is a Canon EF mount lens (not EF-S) and that your camera is a compatible Canon EOS SLR model. Refer to the compatibility section of this manual. |
