Firmware Updates: Use a standard Type-C cable to connect the adapter to a computer or power source for firmware upgrades; follow the instruction manual for step-by-step guidance to avoid update errors.

Lens Compatibility Check: While most Canon EF/EF-S lenses are supported, refer to Viltrox’s official compatibility list for edge cases (e.g., some third-party EF lenses) to confirm full autofocus functionality.

⚠️ Important Notes

Lens/Camera Restrictions: Only compatible with Canon EF/EF-S lenses and FUJIFILM GFX medium format cameras. Do not use with other lens mounts (e.g., Canon RF, Nikon F) or non-GFX Fujifilm bodies, as this may cause damage or malfunction.

Firmware Update Caution: Do not disconnect the adapter or interrupt power during a firmware upgrade—this could corrupt the firmware and render the adapter unusable.

Physical Care: Avoid dropping the adapter or exposing it to water, sand, or corrosive substances. Clean the lens/camera mounts with a dry microfiber cloth before attachment to prevent debris buildup.
