Had a lens fail with just 23 years of use!! If it had gone to 25 years I might not have been too mad. But this is it. Can't stand their quality!!!! I'm just going to sell everything Nikon I have, and buy something else!!! Yea, right! My 28mm f/2.8 AF which I bought in 1994 I believe, will no longer AF. Has something to do with the chip I think. As it focuses freely by hand and by the lens focus coupler. But the body won't even try to focus the lens when connected. Tried on 3 different bodies with body motors. Contacts are clean, but cleaned them anyway. No help. After only 23 years too!!! It's my first Nikon lens to fail, and only 2nd Nikon failure ever. First was SB-600 flash tube. And I have a lot of Nikon gear going way back. Oh, well. Time to go lens shopping again.
