Breakdown of the Techart PRO Leica M to Sony E AF adapter

"Techart PRO adapter is basically a lens adapter with a motor and a printed circuit board, allowing the camera to measure the focus and communicate with the motor. And the motor will move the lens closer or further away from the camera sensor to reach the focal point. The principle is similar to the Contax AX camera that the flange distance is adjusted to reach the focus. The maximum z-shift is 4.5mm which is sufficient to cover the focusing distance for most of the lenses. And the optical performance will NOT be affected for unit focusing lenses."
