Techart has unveiled Techart PRO – the world’s first Autofocus adapter that is able to focus the manual Leica M lenses using the focusing system in Sony a7II and a7RII.

Techart PRO uses z-shift technology which allows the Leica M bayonet to extend and retract. The distance between the lens and the camera sensor is hereby changed in order to reach the focus. The mechanism is quite similar to Contax AX system where the flange distance is changed for autofocusing.

Techart PRO has electronic contacts to communicate with the Sony a7II and a7RII using their PDAF system to focus. The built-in motor will then drive the bayonet forward by a maximum of 4.5mm and reach the focus point for shooting.

Techart PRO adapter weighs only 133g but is able to drive a lens system as heavy as 700g. In addition to Leica M lenses, users can also further adapt lenses with longer flange distance (e.g. Leica R, CY, PK, MD, etc) using add-on adapters to allow autofocus with other manual lenses. Techart PRO supports both AF-S and AF-C modes and it can also serve as a close focusing adapter which can reduce the minimal focusing distance of the lenses.

A complimentary mobile app will be available for users to save 10 sets of lens data to the adapter and perform firmware upgrade via bluetooth. Techart PRO can give users a completely new experience with their manual lenses. The fast and precise focusing allows users to take quick and sharp photos with their favorite manual lenses.
