⚠️ Important Notes

• Lens Compatibility – Not all EF/EF-S lenses guarantee perfect autofocus on M4/3 bodies—test your specific lens first.

• Stabilization Limits – IS support depends on the lens; some third-party EF lenses may not enable stabilization.

• Firmware Updates – Regularly check VILTROX’s website for new firmware to improve compatibility with recent releases.

• Physical Care – Avoid dropping the adapter; metal construction is durable but not indestructible.

• Warranty – Retain your proof of purchase and warranty card for after-sales support.
