    D40, 18-55mm Auto Focus problem

    Hi Guys,
    Been a while since I posted on here, but I was hoping I could get some advice.

    My D40 has been having intermittent focusing issues, this seems to localised to my 18-55mm kit lens.
    It will occasionally make a clicking/grinding noise and will not autofocus.
    I have also had the occasional error, where the camera does not detect that a l lens is attached!!

    I have previously cleaning the contacts on both the camera body and the lens.
    Upon inspection I have found that the contacts on the camera body appear to wearing. Has anyone else experienced this?

    Please see attached image.

    Do I need to send my camera in for a service/repair or is it due for replacement?

    Any advice appreciated.

    Rather big picture, hard to quickly see what it is a picture of

    I am understanding that it is only the 18-55 having this problem and not the 55-200mm VR. I am thinking it would be cheapest just to get a new 18-55 if there is no problem with your D40.

    Resize the picture (no more than 1028 pixels wide is the accepted norm) then we can see what you are talking about.

    Hi Dominic, can I ask for it to be in focus too. It's hard to see the contacts in the above image. Suggest hold the point and shoot that I guess took the shot further back if necessary.

    You absolutely need to send that camera in for repair. Have them remove "Canon" and put "Nikon" on it.

    Something looked strange with the large photo - the close focusing range was beyond the capability of at 18-55 lens. To see it "regular" size, I copied the file and brought up in Photoshop. EXIF data shows was taken by a P&S camera, the Canon Digital IXUS 80 IS, 6.2mm @ f8. Don't know what "Auto Mode 3" is, but does have a "flower" macro mode which would allow such close focus.

    How about a photo, resized to no more than 1050 pixels wide actually taken with the 18-55 lens. Also, check to make sure the lens hasn't inadvertantly been switched over to "M".
