Techart releases TZC-01, an EF-to-Z adapter that offers full autofocus, image stabilization support

17 Jan

In June 2019, camera accessory manufacturer Techart released its TZE-01 adapter, which allowed Nikon Z mirrorless camera users to mount Sony E-mount lenses to their systems without losing the ability to use autofocus. Now, Techart is back at it again with the announcement of the TZC-01, an adapter that makes it possible to mount and use autofocus Canon EF lenses on Nikon Z mirrorless cameras.

Techart says the TZC-01 will work with EF-mount lenses from Canon, Sigma, Tamron, Tokina and Zeiss. In addition to ‘native’ autofocus performance, the lenses will also maintain aperture control, stabilization features and EXIF data. In total, Techart lists 62 lenses it says are proven compatible with the adapter:

Below is a demonstration of the adapter from Richard Wong:

Techart has also included a dedicated function button that lets you save a focusing distance to recall with the press of the button and an accompanying lens dock that will let you upgrade the firmware of the adapter.

The TZC-01 is available on Techart’s website for $ 250.

Techart TZE-01 is the world’s first Sony E to Nikon Z AF lens adapter

20 Jun

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.

At this time, the Techart 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 TechartPro.com.

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.

Pricing and Availability

The Techart Sony E to Nikon Z Autofocus Adapter is currently available for pre-order at our official website (http://www.techartpro.com). The recommended retail price before tax is USD 249/pc.

Techart brings AF to Leica M lenses on Sony’s a7 II and a7R II

12 Feb

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_6307530870″,”galleryId”:”6307530870″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Chinese company Techart has produced an adapter that works with the phase detection AF system of Sony’s a7 II and a7R II cameras to create an autofocus effect for Leica M mount lenses. The adapter ring sits between the body and the lens and uses a motor to drive the entire lens back and forth until sharp focus is found. The company claims focus is usually acquired within a second, and that the depth of the adapter can actually increase the close-focusing range of some focal lengths, allowing users to get closer their subjects.

Focal lengths of 50mm and wider need to be set to their infinity position while mounted on the adapter, and focus is found as the adapter pushes and pulls the lens closer and further away from the sensor. The sensor lets the adapter know when the subject is sharp, and the hunting stops. Lenses with longer focal lengths may need the user to do some of the work with the focusing ring on the lens, and then the adapter will finish the job.

The process only works with Sony’s a7 cameras that support phase detection systems, and the company says the adapter does not work for video. Single shot and continuous AF modes are available however, and the system can deal with lenses that weight up to 700g / 1.5lb. A smartphone app that connects with the adapter allows users to store information about up to 10 different lenses, which the adapter can then communicate back to the camera, so its 5-axis image stabilization system can be utilized.

Techart says that, with add-on adapters, the device can work with other lens mounts that have long flange depth, such as the Leica R, and Contax/Yashica systems. The Techart PRO Autofocus Leica M Adapter for Sony E camera will cost $ 349. For more information and more sample images visit the Techart Pro website.

Press release:

Techart unveils the World’s First Autofocus Adapter for Manual Focus Lens, the Techart PRO AF Leica M lens adapter for Sony E mount cameras

Techart, the Chinese adapter manufacturer who has previously launched the first Contax G autofocus adapter for Sony E cameras, has unveiled the world’s first Autofocus adapter for Manual Lenses named ‘Techart PRO’. The Techart PRO adapter is able to drive the manual Leica M lenses to reach focus by using the focusing system in Sony A7II and Sony A7RII, giving an unprecedented new user experience for all Leica M lenses owners.

Techart PRO has adopted the z-shift technology where the Leica M bayonet is able 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 Sony A7RII and uses its PDAF
system to measure 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 is super light and powerful. The adaptor weighs only 133g and is able to drive a lens system as heavy as 700g. Apart from pairing up with the Leica M lenses, users can also further adapt lenses with longer flange distance (e.g. Leica R, CY, PK, MD, etc) with add-on adapters and enjoy the autofocusing experience 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 is an evolutional product which 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 favourite manual lenses. More product information and testing videos can now be found via our official website.
