    I bought it used 1 year back from ebay...

    Should I just send it back to Nikon for calibration or just buy a new one..I like the range and the color rendition etc...but I really have to stop it down to 5.6 or 8 to get a sharp picture. I thought the lens is just unsharp but later discovered that it is backfocussing...Anybody know how much Nikon charges for calibration?
     
  5. Call...

    Just call Nikon Service and ask. It sounds like something that is common enough that they could ballpark it for you (unless gears have excess slack = new gears being replaced or something else besides just tweeking the glass). Of course I really don't know, just throwing ideas out there.

    I've wondered if mine does or if it is human error.
    Sometimes they look incredible and other times I wonder.
    I've had some head and shoulder shots that have caused a bit of concern.
    So I guess I'm not sure.
     
  8. Mine is an AFD too, but the D part consists of a flexible circuit board on the focusing helicoid and a contact on the focusing ring - there are no active components.
