• Autofocus is Slow or Inconsistent: This can occur with certain non-Sigma lenses. Ensure your adapter has the latest firmware. For video, autofocus may be limited or unavailable depending on the lens.
• Lens Not Recognized / No Electronic Communication: Check that the adapter and lens are securely mounted and that the electronic contacts are clean. Update the adapter's firmware to ensure compatibility with your specific lens and camera model.
• Incompatibility with EF-S Lenses: The MC-11 adapter is primarily designed for Canon EF-mount lenses. Canon EF-S lenses may not be physically compatible or function correctly due to their design.
• Vinheta: If you experience vignetting (darkening at the corners of the image), ensure the lens is fully compatible and consider adjusting camera settings or using a different lens.
