In stock. Ship immediately. The new Canon EF – Nikon Z Autofocus Adapter is the latest groundbreaking product brought by Techart. Taking advantage of the flange distance of Nikon Z mount, Techart developed an adapter to convert all legendary Canon EF-mount lenses (from Canon/ Sigma / Tamron / Tokina / Zeiss) to Nikon Z cameras. The adapter is able to 'translate'  the Canon EF protocol into Nikon Z and  the AUTOFOCUS,  AUTO-APERTURE and LENS STABILISATION functions of the Canon EF lenses can all be retained. Both AF-S, AF-C, AF-F and MF mode will work on the Nikon Z6/Z7. Face and Eye detection, EXIF reading, Timelapse function can also be supported. 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 (Included for FREE). This adapter does NOT work with lenses with no CPU contacts (MF lenses) WARNING: Switch off the camera IF you would like change lenses. Any hot switch will lead to the adapter malfunction. We will NOT provide warranty to any purchase outside this webstore. NO warranty will be provided by us to any eBay/Amazon sellers.
