Hi everyone, I just received my brand new 35 f/1.8 lens today. But the AF motor appears to be non-functional. I've tried the lens in both S and C modes on both a D300 and a D40; the AF motor didn't make a sound or move at all the whole time. (I switch the focus selector around, and nothing happened...) I also tested all 5 of my original lenses on both bodies, the bodies seem to work fine. *The 35 does appear to meter and I can take pictures with it, but it's MF only regardless of what I do with it. *The only possible explanation aside from the lens being faulty is "firmware not up to date". But I doubt a older version of firmware would cause the new lens not to AF... Please let me know what you think. Thanks!
