Autofocus performance depends on the specific EF lens and camera body combination. While the adapter is designed for seamless integration, electronic communication for AF is facilitated by the camera and lens firmware.

Yes, manual focus EF lenses can be used. The adapter provides a secure physical connection, and you would operate focus and aperture manually on the lens itself.

The adapter is designed for EF mount lenses. While some EF-S lenses may physically fit, their performance and compatibility are not guaranteed due to differences in image circle size and electronic communication. It is recommended to use standard EF lenses.

The support foot helps to transfer the weight of heavier lenses away from the camera's lens mount and onto a tripod or other support system, increasing stability and reducing wear on the camera mount.

The flocked coating on the inside of the adapter absorbs stray light, reducing internal reflections that can cause flare and reduce image contrast, especially when shooting into bright light sources.

No, the adapter features an active-locking system designed to eliminate any play, gap, or wiggling, ensuring a solid and secure connection between the lens and the camera body.

Ensure the lens is securely locked onto the adapter and the adapter is securely locked onto the camera. Check for any debris on the lens or adapter mount contacts and clean if necessary. Verify camera firmware is up to date.

Re-mount the adapter and lens, ensuring they are fully twisted and locked into place. Check if the active-locking system is engaging properly. Ensure no foreign objects are obstructing the mounting mechanism.

Verify that the adapter's interior flocked coating is clean and free of dust. Ensure the lens is properly focused and the adapter is maintaining accurate infinity focus. Check for lens element smudges.

Try removing and reattaching the lens and adapter. Consult your camera's manual for specific error code interpretations. Test with a different EF lens if possible to isolate the issue.
