D300 Problems - What went wrong?

    There was I taking photographs for the current [SI] (On the road) with
    my camera mounted on the top of a monopod which I was holding upside
    down so my 70-200 lens could take photographs just above ground level.
    The camera too was upside down. I was triggering the camera through a
    remote cable while holding the bottom of the monopod at about hip
    level. The camera was resting on my foot with the lens steadied
    against the lamp standard against which I too was leaning.

    The camera is a D300 with a near-new SanDisk 32GB Extreme CompactFlash
    60 MB/s memory card through which about one thousand photographs had
    already passed. There were about 12 shots on it when I started my
    expedition.

    There was I happily snapping away and every now and then I would lift
    up the camera and examine the rear view screen to see how badly I had
    been doing. Suddenly I found that pressing the view button produced no
    effect. The screen remained black. It remained black when I pressed
    the menu button also. Turning things on and off made no difference.
    Neither did pressing the shutter button. Suddenly 'click - crunch',
    the camera took a photo and everything worked again.

    This happened two or three more times and then I experienced a total
    lockup which did not eventually come right. The section of the control
    window on top which normally displays the number of exposures left
    showed 'r9' which means that the buffer has room for 9 more exposures
    with the current setup. While I was looking the camera went
    'click-crunch' again and the 'r9' changed to 'r8'. But still the
    camera wouldn't work. At this point I removed the battery for a minute
    and then reinserted it, but no change.

    As it happened I was only about a 100 yards from the very
    knowledgeable Camera & Camera who had sold me the camera in the first
    place so I took it into them. They scratched their collective head and
    eventually decided there was a fault. At this point I decided to take
    the camera home and carry out some research to try and get to the
    bottom of the problem.

    I removed the 70-2-- lens and fitted my normal 16-85. The remote cable
    was removed and the camera was packed in its bag. When I got home I
    had lunch, then removed the camera from its case and found sweetness
    and light had returned. There was no sign of any problem and the
    camera seems to be working correctly.

    My question is, can anyone throw any light on what went wrong? I'm
    inclined to suspect the memory card but I have no real basis for this.
    What worries me is the possibility of it happening again.

    How is the camera set to function if no card is installed? Try
    changing that if you think the card may an issue. If had somewhat
    similar issues of not taking photos as the mount on my 70-200 f.8 VR
    has aged and doesn't make sufficient contact at the electrical
    contact. Have you tried cleaning those on the camera and lens?

    I don't know the answer, but it seems that key factors were attaching
    a heavy lens to the camera, and then holding it in an unusual position
    (upside down on your foot). Maybe the position caused stress which
    affected the electrical contacts in the lens mount, or maybe even the
    mirror or shutter. Or maybe this episode is unrelated to anything you
    were doing.

    You are not alone. I have had the same issue at random, as have others:

    It seems Nikon is aware of the issue, but has no fix.

  5. Contact trouble between lens and camera? If the contacts are
    at the bottom of the mount --- which is the top then --- and a
    slight give in the bayonet lets them get apart a bit ... a 70-200
    isn't the lightest lens.

    That's a possibility. I'll try cleaning them as they haven't been much
    used. The trouble is if the problem doesn't come back I won't know
    whether or not I really fixed it and it was some other cause that went
    away.

    Yep.

    The monopod was attached to the lens. It was the camera resting on my
    fooot. That could have overloaded the lens/camera connection.

    My problem is slightly different. While it was misbehaving it wouldn't
    even take photographs. The camera seemed totally unresponsive to the
    operation of any control except the on/off switch.

    I have experienced this type of problem with a D90- so its sort of the
    same range of camera.

    My D90 is a one lens, happy snapper trip camera, at about 9 months old,
    1800 activations. Without notice virtually the same thing happened. The
    camera did not have a country of origin warranty to refer it back to
    Nikon so I had to trouble shoot the problem.

    I read through all the threads from just about all the sites and no one
    had an answer. Only hypothetical reasons which only a committee offer.
    Yes I tried silently all the hypotheticals and none worked. You may
    want to refer to the D90 problems in forums although none worked for me.

    I was changing batteries, cards, no result even reset the default
    settings, one thing that I did not change, was the lens. within all this
    testing. (the camera came with the 18-105 lens and had never been off
    the camera.)

    The whole thing was repeatable within 5 frames and showed an error.

    As a last resort was to try another lens, so with another lens, the
    camera kept working. So I replaced the original lens back on the
    camera. It is now about 4 years old and has not had a glitch since. I
    didn't clean any contacts but removing the lens may have.

    The only reason that I can put it down to is dirty contacts either on
    the lens or the body. ( the body did not show a lens error and I'm
    unsure what the error message was now but something like yours which was
    sort of unrelated to what was happening.

    So my best bet with your camera maybe the lens/body contacts.

    Some further into in my case. Has happened with all my bodies
    (D70/D200 & D300) and got progressively worse as the lens and bodies
    got more wear. Appeared to get worse with the use of a TC. No issue
    with any other lens including a 200-400 f/4 VR. I've been meaning to
    send in the 70-200 to have the lens mount plate replaced as the
    200-400 has mostly relegated it to my bag. One other symptom in my
    case was either changing or loss of proper control of the aperture as
    indicated by the f-stop setting changing while the r-buffer number was
    displayed. Inputting upward force on the objective of the lens seemed
    to help some which to me indicated bad contact.

    Maybe the key point in your original post is that the camera was upside down,
    which might exaggerate any problems with the adjustment of the mirror. A
    binding mirror could certainly be the cause of a blank. (Just one more reason
    to look forward to professional-quality mirrorless cameras.) Have you run any
    follow-up tests with the camera in that position?

    Did you also say that the exposure counter actually counted more pictures than
    you took, even if you include the blanks? If so, that sounds more like an
    electrical problem.

    And that you may have been letting the camera body assume too much of the
    weight of the lens.

    That's a common symptom while the camera drains its buffer into the card. But
    I sense that in your case the delay was too long for that to be the issue.
    Unless maybe the card wasn't making good contact (which I guess was one of
    your original suspicions).

    I pretty much have now carried the 200-400 f/4 the same way on the
    D300 with a TC-14 behind it for several years and have no issues with
    it. Put the 70-200 on it with or without the TC and the problems
    persist. As I said I believe the issue is with the mounting hardware
    of the 70-200.

    All I've done is reach a decision that in future I'm going to avoid
    the sustained use of the camera upside down.
    No I didn't say that. What it did it did do is tell me the number of
    shots the buffer could hold with the then current configuration. That
    should require half pressure on the shutter button but I wasn't
    touching it at the time.

    Weather permitting I'm going to try it again tomorrow with a different
    lens. Whether I do it with the camera upside down is another matter.

    Aha! I will now focus my attention on the lense rather than the fact
    that the camera was upside down (although that could still be a
    factor).

    So your recommendation? buy a lighter lens?
