Chinese accessory maker Techart has announced the TZE-01, the first autofocus adapter for using Sony E-mount lenses with Nikon's Z series cameras. Techart describes the adapter's design as having been 'difficult' due to the Nikon Z-mount's flange distance being just 2mm shorter than the Sony E-mount.

The Techart TZE-01 features a PCB sandwiched between the electronic connectors on both sides of the adapter, making it possible to use both the Sony E-mount Auto Aperture and Auto Focus lens functions, even when using the Nikon Z's Face & Eye detection mode.

The TZE-01 finds room for a PCB to 'translate' between the Nikon and Sony communication protocols, allowing Nikon cameras to autofocus E-mount lenses.

Depending on which Sony E-mount lens is used, Techart claims its adapter allows the use of phase-detect AF to offer autofocus accuracy and speed 'very close to (if not better) [than] native Z-mount lenses.' The company claims other functions, including lens-based image stabilization are also supported.

Performance varies between lenses but if it's generally up to a reasonable standard, this adapter considerably broadens the lens choices for Nikon users. It could also significantly lower the barrier to changing systems for Sony users, if Nikon produces a body they're interested in.

The company says it adapter works with Sony E-mount AF lenses from Sigma, Sony, and Tamron / Zeiss. The adapter is shipped with a lens dock for firmware upgrades that will add additional lens support in the future. The TZE-01 adapter is available to purchase for $249 USD from

Techart unveils the World’s First Sony E to Nikon Z Autofocus Adapter with a thickness of 2mm

Guangzhou China, Jun 20, 2019 – Techart, who has previously launched the first autofocus adapter for manual lenses, has unveiled another groundbreaking product, Techart Sony E to Nikon Z Autofocus Adapter (TZE-01). The new TZE-01 is the world’s first autofocus adapter that allows Sony E-mount lenses to retain the Automatic Focus functionality when used on Nikon Z6 and Z7 cameras.

The flange distance of Nikon Z-mount is only 2mm shorter than Sony E-mount. This makes the design extremely difficult, let alone an electronic adapter where a chip and the connector pins have to be squeezed into. Techart has managed to pull it off and develop one which include connectors of both sides and a PCB board with chip to “translate” the protocol of the lens and the camera.

The Techart adapter enables both Auto Focus & Auto Aperture functions of Sony E mount lenses to be used on Nikon Z6 and Z7. AF-S, AF-C & MF mode are supported in both still & video shooting. The incredible Face & Eye Detection of Z-mount cameras can also be used. Other functions like lens vibration reduction and timelapse can also be used. Phase-detect Autofocus is adopted to guarantee both AF accuracy and speed to be very close to (if not better) native Z-mount lenses. Please note that functionality may vary when different E-mount lenses are used.

Nikon Z system is a relatively new system and users do not have a very complete lenses selection. Unlike the system of Sony, most lenses manufacturers have been releasing lenses in E-mount and so the selection is complete. The new Techart adapter currently supports most of the Sony, Sigma, Tamron & Zeiss AF lenses with Sony E mounts including some of the best sellers like Tamron 28-75mm, Batis 25mm f/2, Sony 24mm f/1.4 GM and Sigma 35mm f/1.4, etc.

The new Techart TZE-01 adapter comes with a lens dock for firmware upgrade. Simply connect the PC/MAC via a Micro USB cable (not included) and the firmware can be updated via the Techart App. Techart is currently working to support more lenses.
