New TechArt PRO adapter gives autofocus to M-mount lenses on Sony A7 II / A7r II

Today, SonyAlphaRumors shared some additional information about an upcoming adapter called the TechArt PRO that will make it possible to autofocus with M-mount lenses on compatible Sony E-mount cameras. (We previously wrote about the development of the adapter a few weeks ago.)

According to the official TechArt PRO website, the adapter is meant for the Sony A7 II and A7r II and will work not only with all M-mount lenses from Leica, Zeiss and Voigtlander but also other mounts like Leica R or C/Y if you use other adapters along with it.

The adapter combines a quick and accurate motor with a printed circuit board that allows the camera to measure focus and communicate with the motor. The company claims that it can focus in less than a second most of the time, and the resulting image quality remains unchanged. It supports S-AF and C-AF and even improves the close focus capabilities of manual focus lenses. Plus, there is also support for 5-axis stabilisation.

At only 133 grams, it won’t add much extra weight or bulk to your A7 camera, yet it can drive a lens system that weighs up to 700 grams.

Below are the complete specifications found on the website:

  • Objective lens mount – Leica M mount
  • Camera mount – Sony E
  • Compatible cameras – Sony A7 (II) , Sony A7R (II)
  • Maximum bayonet extension – 4.5mm
  • Supported Focusing Mode – AF-S / AF-C

  • Maximum weight supported – 800g (* Handheld support recommended for heavy lens)
  • Lens data record in EXIF – 10 sets
