I have used my Nikon D60 for about 6 years now, with AF-S DX NIKKOR 18-55mm f/3.5-5.6G, and AF-S 55-200mm Nikkor f/4-5.6G lens, and the autofocus has been working fine this entire time.
However, I recently used the AF Nikkor 50mm f/1.4D lens for a few days, which of course requires manual focus. But when I switched back to my two older lenses, the autofocus would not work anymore. The motors would rotate but it just wouldn't focus. In the past, if that happened, all I needed to do was detach and reattach the lens, but that didn't help. I tried to clean and wipe everything but still doesn't work.
Although I thought that initially putting on the 50mm lens was more difficult, as it felt like a tighter fit, and now it feels much easier to put on my older two lenses, and it just feels looser. Could it have anything to do with that? like a problem with the contact between Camera and Lens?
Any thoughts? Much appreciated on any suggestions!
