Instruccions de funcionament
This is a manual adapter. Lens functions that rely on electronic communication with the camera body (such as autofocus, AE metering, and image stabilization) will not function.
Focusing and Exposure
- Enfocament manual: Focus must be adjusted manually on the lens.
- Exposició: Configureu la càmera a Aperture Priority (Av) mode or Manual (M) mode to control exposure.
- Control de l'obertura: If your C-Mount lens has a manual aperture control ring, adjust it directly on the lens. If the lens does not have a manual aperture control ring, the aperture will revert to its default position (either fully open or fully closed, depending on the lens design).
Gen10 Focus Confirmation Chip
The integrated Generation v10 Focus Confirmation Chip "tricks" the Canon EOS camera body into recognizing an EF-compatible lens. This enables the camera's visual (green dot in viewfinder) and audible focus confirmation indicators to function, assisting with manual focusing.
Nota: The chip provides focus confirmation, but does not enable autofocus or electronic aperture control.
Consideracions importants
- No Infinity Focus: This adapter does not allow for infinity focus. It is designed for macro and close-focus applications only.
- Vinyetatge: Due to the image circle of C-Mount lenses, significant vignetting may occur, especially on full-frame camera bodies.
- "Focus-By-Wire" Lenses: Lenses that require power to engage their manual focus rings (e.g., Canon STM or Nikon AF-P lenses) will not be able to focus when used with this manual adapter, as the adapter does not provide power.
- Crop Factor: The effective focal length of the C-Mount lens will be affected by your camera's crop factor. For more information, refer to the Fotodiox Knowledge Base.
Manteniment
- Neteja: Use a clean, dry microfiber cloth to wipe the adapter. Avoid using harsh chemicals or abrasive materials.
- Emmagatzematge: Store the adapter in a dry, dust-free environment when not in use. Keep lens caps on both ends if possible.
Resolució de problemes
"Error Lens Not Attached" Message
Some Canon EOS cameras may display an "Error Lens Not Attached - Check lens" message when a manual adapter is used. To resolve this, ensure your camera settings are configured to allow shooting without a lens. Refer to your camera's instruction manual for specific settings, or consult the Fotodiox Knowledge Base for potential solutions related to various camera brands.
Problemes d'enfocament
- Ensure the lens is securely attached to the adapter and the adapter to the camera.
- Remember that this adapter does not allow for infinity focus; it is for macro and close-focus only.
- Verify that your camera's focus confirmation indicators are active (green dot/beep) if the Gen10 chip is functioning correctly.
