Electric contacts are also incorporated into the adapter's design and maintain full communication between the camera and lens, as well as support metadata transmission and use of Dual Pixel AF with select Canon EF lenses. The adapter directly attaches to RF-mount camera bodies, and four screws and a split locking collar are included for a more secure attachment.
