I just purchased a 300mm 2.8 lens on Ebay from a retired staff photographer for the Star Tribune. The lens is in mint condition. I shot with it the day I received it and it worked perfectly with my D1H. The next day, I switched it to manual and it was smooth. I switched it back to AF and it started making a loud screeching sound when focusing. It looks like the distance ring is getting stuck when trying to focus. Has anyone ever encountered this problem???
Please help!
