Techart TZE-01 E-Mount to Nikon Z-Mount adapter Thu, 20 Jun 2019 06:31:39 -0600 Vitaliy_Kiselev 22209@/talks/discussions image

Available at -

The new Sony E – Nikon Z Autofocus Adapter is the latest groundbreaking product brought by Techart. We take advantage of the 2mm difference in flange distance between Sony E and Nikon Z mount and developed an ultra-thin adapter to convert the lenses in Sony E mount into Nikon Z. Techart also manage to incorporate a CPU chip into this tiny space which can ‘translate’ the protocol of Sony to Nikon so that the AUTOFOCUS, AUTO-APERTURE and LENS STABILISATION functions can all be retained.

Both AF-S, AF-C and Eye-AF mode will work on the Nikon Z6/Z7. Phase-detect AF is used and therefore the AF speed is on par with using native Z mount lenses on the cameras. Firmware is upgradable via separate lens dock.

Samyang / Rokinon / Sigma AF lenses are currently NOT supported.


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 . The recommended retail price before tax is USD 249/pc. Free shipping will be provided during the promotion period. Delivery will start from late June. 1-year warranty is included.

Olympus MC-20 teleconverter Wed, 19 Jun 2019 05:57:55 -0600 Vitaliy_Kiselev 22197@/talks/discussions image


Expand the Field of Photography with Portability and Superb Image Quality of the Master Lens

Olympus is pleased to announce the M.Zuiko Digital 2x Teleconverter MC-20. This teleconverter doubles the focal length of the master lens, and features dustproof, splashproof and freezeproof (-10°C) professional weatherproof construction for outstanding optical performance ideal for even the most severe environmental conditions. By doubling the maximum shooting magnification of the master lens, this teleconverter further expands the field of photography in super telephoto macro shooting. This product is compatible with the M.Zuiko Digital ED 40-150mm F2.8 PRO and M.Zuiko Digital ED 300mm F4.0 IS PRO, as well as the M.Zuiko Digital ED 150-400mm F4.5 TC1.25x IS PRO, which is currently under development.

Super Telephoto and Super Telephoto Macro Shooting

Just like the M.Zuiko Digital 1.4x Teleconverter MC-14, the M.Zuiko Digital 2x Teleconverter MC-20 maintains the excellent imaging performance of the master lens while doubling the focal length, making it possible to capture intense shots of subjects that are usually difficult to approach, including small birds and animals. When attached to the M.Zuiko Digital ED 300mm F4.0 IS PRO, handheld super telephoto shooting at 1200mm equivalent (35mm equivalent) is possible.

When attached to the M.Zuiko Digital ED 300mm F4.0 IS PRO, the MC-20 allows the user to shoot near actual size at 0.96x (35mm equivalent) from the maximum shooting magnification of 0.48x. With performance like this, the photographer can capture close-up photos from far away without disturbing subjects that are sensitive to people, such as insects. Utilizing Focus Stacking results in photos that are in focus across the entire image, even on super telephoto lenses, which tend to have a shallow depth of field.

Outstanding Optical Performance

A 9-element, 4-group lens construction with an HR lens helps suppress various types of aberrations including chromatic aberration while maintaining the excellent optical performance of the master lens to double the focal length. The design also helps prevent ghosts and flares for superb image performance, thanks to ZERO coating.

Reliability to Capture the Moment

The master lens is designed to deliver excellent performance and dependable reliability, even when an Olympus teleconverter is attached. Virtually no loss in autofocus speed makes it possible to capture split-second photo opportunities using FAST AF performance. The dustproof, splashproof, and freezeproof professional weatherproof construction, coupled with powerful 5-axis image stabilization and FAST AF ensures that the user captures their shot even in the most severe environments.

Compatible Lenses

  • Zuiko Digital ED 40-150mm F2.8 PRO
  • Zuiko Digital ED 300mm F4.0 IS PRO
  • Zuiko Digital ED 150-400mm F4.5 TC1.25x IS PRO (under development-planned for launch in 2020)

Pricing and Availability

The Olympus M.Zuiko Digital 2x Teleconverter MC-20 ships with the body cap BC-3, lens cap LR-2 and lens case LSC-0603 and is available now with suggested retail prices of $429.99 USD and $559.99 CAD.
