Nikon D70s can't take the heat

    Greetings:

    I recently toured parts of India and the humidity was low but the
    skies were sunny and the temps were around 110F. While in the sun and
    heat, my D70s would periodically lock up. What would happen is that I
    would hit the shutter button and there would be no response. The
    display would read "error." Turning the camera off and then back on
    didn't help. DOF preview would also not work. You could hear the
    diaphragm closing up but no light was getting through (at least not
    getting through to the viewfinder). Only if I hit the shutter button
    again would the camera come back to life. At that time, the mirror
    and related mechanisms would cycle once rapidly (and produce a blank
    image on the card) and then the camera would start working normally
    again -- until the next time the error occurred, which was sometimes
    only a few shots later. I had to walk around mentally prepared to
    have to hit the shutter button twice rapidly on any given shot since I
    never knew when the camera would jam up. It's like the mirror was
    stuck. But I'm not sure exactly. Indoors and in cooler temps, the
    camera would behave Ok -- no errors. Anybody encounter anything
    similar?

    Thanks.
    Kevin

    It could easily be the heat, which is no friend to cameras. I used a
    Nikon D70 in the Phlippines for 18 months, but temperatures rarely get
    above 95 F. I had more problems with humidity, dust, and just knocking
    it around.

    If you are going to be in heat like that it might be a good idea to
    keep the camera in a styrofoam cooler when you are not using it.

    Max operating temperature for the D70s is 104 F. It does not have to
    actually be 104 for it to reach that temperature, what with its black
    body. Just leaving it in the sun will quickly increase temperatures
    enough to damage the camera.

    The D70 is more tolerant of heat than some other cameras I have used
    (notably Fuji, which is extremely heat sensitive) but it does have its
    limits.

    This is a very relevant issue.
    Although I try to keep my dSLRs in a back pack or other covering when not in
    use they heat up very rapidly on hot summer days when you are in direct
    sunlight, even after just a few minutes dangling around your neck.
    Apart from the manufacturer's specs about operating temps, which could be
    based on who knows what, has anyone published any systematic stress tests on
    these things?

  4. I .too recently returned from India with my Canon 400d and although
    temperatures never hit 110, they did hit 100, and I didn't note any
    operational errors, but that said, I did keep my camera packed pretty tight
    in it's bag whilst not in use as I was very mindful of a mechanical
    malfunction at those temperatures.

    Higher thermal contraction and expansion in plastic compared to metal
    bodied cameras is likely the reason. Some kind of binding is occuring
    with expansion due to heat.

    Hi I had a similar problems with my camera buy I recently found a great tech support site that gave me some tips of how to prevent it. They also have live free chat support where you can chat with their experts.

    Here is the page for Nikon D70 Support

    Good luck

    And pressing the shutter button again cooled the plastic just enough
    to let it work?
    How intellignet of Nikon to take this into account.

    Thanks for the insight. Indeed, the specs in the back of the manual
    say 104F. Kudos to Nikon's environmental-testing team. :)

    I didn't realize how hot the camera was until after it started
    producing errors. Then I felt the back of the camera -- yeah, quite
    hot. Couldn't put it away, though, as I was walking around in a crowd
    and needed to keep shooting with it. I guess I can't complain,
    though, since you said that some cameras are worse. Maybe, for next
    time, I'll attach a mini umbrella to it. Or, better yet... maybe
    Nikon will put out an "iPOD White" version, like what everyone else
    seems to be doing with their products these days. Or, better still,
    chrome. That would be funky, wouldn't it? You could bounce your
    flash off your own camera.

    Anyhow, thanks again.

    Well, what CJ Campbell said and what I also saw in the manual, the max
    operating temp is listed at 104 F. So, based on my experience, that
    spec seems relatively accurate. I've put the camera away for humidity
    but have never had it in that kind of heat before.

    Thanks.

    In the future, I, too, will be mindful of a mechanical malfunction at
    those temperatures. :)

    Thanks.

    Lets say Nikon (likely) engineered the internal mechanisms to work
    within a 1 or 2 thousands of an inch leway.
    Now, you have the plastic expanding beyond that tolerance with
    increased temps. The metal (what there is) attached to the plastic
    all of a sudden has less room to move in, no slack and binding
    occurs. This is the REASON even all metal, multi-thousand dollar
    telephotos like Nikon's 400mm f2.8 use compensating cells for the
    elements, so they can accommodate the expansion and contraction of
    aluminum with a temperature change. Plastic is 100x worse.

    Thanks; but I don't understand your explanation of how the heated
    camera body material itself was helping to cause the error. Was it
    distorting the shutter mechanism?

    The D200's body is composed of magnesium and the operating temps are
    the same as for the D70s (according to the manual's specs anyway).

    Operating temps are usually based solely on the LCDs and electronics,
    not the mechanicals.

    And no one but you knows this, so obviously Nikon can't take that into
    account.
    Do you enjoy showing your ass like this?

    Some of Canon's cameras are silver-colored, although I think maybe only one,
    the Rebel XTi, is currently available in both silver and black. I bought XTi's
    in the two colors for my wife and myself so that we could tell them apart.

    Good strategy. Nikon also has it. I've seen some D50 pictures in
    ads that were silver & black, and Magic Lantern's "Nikon D50" guide
    also has a few large pictures of the silvery body. It's amazing how
    bad it looks, but I suppose that it will help discourage theft. :)

  18. Wrapping the lens and body in aluminum foil does the same thing.

  19. Actually, it is quite more effective, for several reasons obvious to those
    reasonably skilled in the area of heat transfer.

  20. Yep, agreed! The reflective surface of the foil will keep the lens/body
    from absorbing heat and getting hot. This is why I find it hard to justify
    buying any "white" lenses when the old Nikkors will work just fine.

    On a side note: You haven't wrapped your 200-400mm VR in one of them silly
    lens coats, have you?
