Megadap ETZ21 Por+ New Version Auto Focus Adapter Compatible with Sony FE Sigma Tamron FE Series Lens to Nikon Z Mount Camera Zf Z9 Z8 Z7 Z6 Z6III Z7II Z6II Z5 Z50 Z30 ZFC

Out of the box this thing worked with my Z9 and existing Sony lenses, with the exception of the 100mm STF. All other lenses I own are fully compatible. Great product for you who have Sony mirrorless and are moving to Nikon.

works, but be careful if using zoom lenses. The constant zooming in and out might jiggle the lens mount and adapter causing the camera to loose connection with the lens. to re-gain connection you need to do a battery pull. This can become frustrating or unacceptable in professional scenarios where timing is important. therefore I can't recommend it for any professional work, however for more leisurely photography it should suffice. Also, I should encourage it for prime lenses and avoid zooms for the previously mentioned issue.

Center sharpness is good but the corners are unuseable.
