Leica Autofocus Capabilities. No, it’s not a typo. And no, it’s not witchcraft. The Techart Pro Adapter allows the camera to measure focusing distance and communicate with its motor. The motor then physically shifts the lens’s position up to 4.5mm on the Z axis, enabling autofocus even on manual-focus lenses. This adapter supports AF-S and AF-C focusing modes. If you set the lens to its close-focus position, you can use this adapter’s extension to get macro capabilities.
