Re: auto focus problems
Generally, a Nikon AF body - lens needs something of contrast to focus on (i.e., the tux of a groom) and with a white wedding dress, the autofocus tends to go 'nuts.' You could pick a spot (a pew) to focus on and then turn AF off: during the walk-down-the-asle, just shoot when the person hits that spot. In a less-than-bright church, maybe your eyes and digital are not a prime match. You could return to a film camera -- the F100 does well in lower light.

You did not say which lens or lenses you are using, but most auto-focus lenses have a switch for selecting manual or auto-focus. First, check your camera's menu settings to make sure auto-focus is enabled and then your lens to make sure you did not accidently leave it in the manual focus position? If it is in the auto-focus position and still not taking sharp pictures, switch it to manual and see if you can get it to focus correctly. It is also possible that your auto-focus alignment is out because your camera was bumped, jolted or dropped. If realignment is necessary, you can send the camera and lens to Nikon for repair or find a knowledgeable camera repairman.
maybe there is something wrong with your focus flex cable or focus pole. so it brings focus trobule when you are taking the pic. you can buy the flex or pole by yourself or send it to the camera repair center. it will not cost too much money. the parts is not expensive. www.skiliwah.cn/ http://www.digitalcamera-parts.net/
Seems possible that the servo control /main processor control is faulty and will need help from Nikon service , It will be better to get a evaluation for the fault and so we can have a consenses on the fault.
get estimate and decide.
We tried the same lens on another Nikon (D90) and auto focus did not work.
We mounted a new set of lens on the original D40x, and it worked.
Turns out the 2 year Nikon lens (18mm-135mm) was bad. Nikon lens have a 5 year warrantee. The lens will be sent back to Nikon with no service or shipping charge.
Does the camera body has a M/AFswitch? it would be located in front on the left side if that accidently gets changed to M your lens will not AF any more until you change it?? I know it sounds so simple but who knows!! Barry Brown www.coralreefphotos.com
I had the same problem. My issue was with all my lenses. I solved it by going to the menu and selecting the custom setting menu (pencil icon). Then from the right menu select the AE-L/AF-L and press OK. Then make sure it is set on AE/AF Lock. Presto...all my lenses worked on auto-focus.
