How to use

To use the adapter, first attach it to the lens mount of your Sony camera body by aligning the index marks and rotating it until it clicks into place. Once the adapter is secured to the camera, attach your Canon EF lens to the front of the adapter, ensuring the lens mount index marks are aligned. The camera should automatically detect the lens, allowing you to adjust settings such as aperture directly from the camera interface. Always ensure the camera is powered off before attaching or detaching the lens and adapter to prevent potential electrical issues.

What to consider before purchase

• Verify if your specific Canon EF lens model is supported for full autofocus functionality.
• Consider the weight balance of larger lenses when mounted on smaller Sony camera bodies.

Usage recommendations

For the best performance, it is recommended to keep both the camera and the adapter firmware updated to the latest versions provided by the manufacturer. Regularly clean the electronic contact pins with a soft, dry cloth to ensure stable communication between the lens and the camera.
