That's weird. I'm not super familiar with Nikon AF gear, the F6 is my first and only Nikon SLR with AF. How you don't run into anymore strange behavior!

Had a weird AF issue with my F6. AF was fine with the Sigma Art. Then put the Nikon 105 1.8AIS on it - manual focus lens. Then put the Sigma lens back on. Now no AF. I made sure the settings were correct on the camera. Removed battery etc. No AF. Took lens off, put it back on, no AF.
Then put a Nikon 50 1.8G lens on the F6. AF works again. Replaced the Nikon lens with the Sigma AF lens. Now the AF works again!
Hmm.
