EOS-350D locking up sometimes

    I've experienced some strange behaviour from my Canon EOS-350D a few
    times, and it happened again yesterday. At first it won't shoot when I
    press the shutter button. I tried to change the program mode, turn the
    camera on/off. Even remove and re-insert the memory card. I finally got
    a -99 error message, whatever that means.

    At last I decided to remove the battery, then put it back in which
    solved the problem and I was able to take pictures again. Is something
    wrong with my camera or is this the sort of thing that happens
    occasionaly with digital SLRs?

  2. Have you updated the firmware?

    According to the manual:
    "Err 99: An error other than the above [i.e. 01, 02, 04, or 05] has
    occurred. Remove and re-install the battery. This error may occur if
    you use a non-Canon lens and the camera or lens does not operate
    properly as a result."

    If it said "Err -99", that's not listed in the manual.
    It's never happened with mine, but I've only taken about 9,000 shots
    with it so far.

    Have you checked the manual for the meaning of the error?

    This is a normal error on the 300D, 350D and the 20D and usually means there
    is a problem with your lens.

    What kind of a problem with my lens? Yes, it is a "non-original" lens
    (Sigma 17-70mm f/4-5.6), but it's only happened a few times even though
    this lens has been used 99.9% with this camera. If the lens is
    "non-compatible" I assume it shouldn't work at all, or I should be
    getting error messages all the time, which isn't the case.
    I also have a Canon 70-200 f/4L but have only recently bought it and
    used it a couple of times. I'll continue using the Sigma 17-70 most of
    the time as it's great for everyday use as a "walkaround" lens, while
    the Canon 70-200 will be used for special situations where I need a lot
    of zoom. Some lens though!!!

    As for the actual error message, I can't recall if it was -99 or 99.
    I'll take a note of it if it happens again, but the error message
    didn't show up until after a while. The first thing that happened was
    that the camera wouldn't take a picture when I pressed down the shutter
    button. I then turned the "program" button to different programs,
    turned the power on/off but nothing helped. Even removing the memory
    card and reinserting it didn't help, but I think that's when the error
    message came up.
    After removing the battery, then re-inserting it solved the problem
    (for now) and the camera seems to work fine again.

    Someone asked about the firmware. I have version 1.0.3 which was what
    the camera came with when I bought it. I don't know of any newer

    With a newer lens like the 17-70mm I would not have expected a problem but
    removing and reinstalling the lens may help.
    Pete D, Sep 11, 2006
  8. That may have been because it couldn't find focus.

    I then turned the "program" button to different programs,
    That's the general solution.
    Check Canon's website.
    Yes, it could.

    Time for the usual warning about Sigma lenses on Canon bodies?
    The comments I've seen as that Sigma lenses may not always work as expected
    on EOS bodies.
    A friend has a Sigma 170 - 500mm lens which she tries to use on an EOS30.
    The tow work together only in some modes. I _think_ they work in Av mode (or
    Tv mode) but not in P mode or the icom modes.
    I tried the lens on myEOS 350D and found they would sometimes work in one or
    two of the body'd modes but not consistently.

    The problem is that Sigma have not got themselves licensed by Canon so Sigma
    may not see the full internal workings of the EOS mount. In their favour,
    Sigma are always willing to replace the chips in their lenses in order to
    bring their version of the EOS mount up-to-date. They cannot always do this
    and, in such cases, I have heard that they will do quite good trade-ins.

    I had my 350D/XT lock-up....did nothing when the shutter release was pressed....
    one time when I had the program selector set for "Aperture" and the
    aperture was set to some ridiculous value. I changed to something more
    realistic for the lighting conditions and it unlocked and worked OK. No
    error messages and the internal flash was set to OFF.
    It's only happened that one time and I thought that was the way it was
    supposed to work.

    This is normal, and documented, behaviour. If the green exposure light
    in the viewfinder is flashing, then the shutter release button won't
    work. Only in M mode (ICBW) can you take pictures with totally
    unrealistic settings.

    If it's an old sigma lens, you will get this ERR 99 whenever the lens
    is used the the currently selected program calls for an aperture other
    than the lens's maximum aperture.

    I have 2 such old Sigma lenses myself. I can only use them at f/2.8
    which is a bummer. Your sigma may be chip upgradeable.

    See Sigma FAQ 7 http://www.sigmaphoto.com/faq/faq.asp?navigator=3

    Canon changed the aperture signalling algorithm cleverly rendering the
    non-licensed sigma lenses useless for any use other than their max

    I had the Err 99 message ( general lens error) come up about two weeks ago
    on my 350D and Sigma 105 - 400 (chipped by sigma)
    After pressing the shutter release, it sounded as though the shutter had
    jammed for aprox 3-4 sec, but when I checked the image, the exposure etc was
    fine, which meant that it was not the mirror that jammed ( or it would have
    overexposed) but the blades of the diaphragm (Iris/aperture blades) in the
    lens itself.
    I have been using the lens for about one year now, and it has only happened
    the one time so far, so I am assuming it was due to a speck of dirt etc that
    has worked it's way into the lens.

    Whether the diaphragm jamming could cause the rest of the camera to lock up
    for longer than a few seconds I'm not sure, but as it is only happening
    occasionally, dirt in the lens might be a possibility, or dirty lens to body
    Sorry I haven't got a definite answer, but I thought my problem might be
    worth a mention.
    Good luck

    But the Sigma lens I have is certainly not an old one (Sigma 17-70 f

    As the EOS-350D is (or was, now that the 400D is replacing it) sold in
    the same time period as the Sigma lens they would be stupid to make it
    incompatible. I read several tests and reviews before buying the lens,
    yet none of those mention incompatibility issues with the 350D.

    Are you saying I made a bad decision and should have gotten a Canon
    lens instead?
    The problem with that is that I couldn't find any equivelant Canon lens
    giving good quality, an "allround" focal length that I needed at a good
    price. The Sigma 17-70 seemed like a much better choice.

    So if the lens is indeed incompatible with my EOS-350D, what should I
    do? Contact Sigma who will re-program the lens (for free)?

    Regarding compatibility issues I found an interesting chart at the
    Sigma UK website:

    It confirms that my Sigma 17-70mm is compatible with Canon's EOS-350D.

    Do I still need to worry about lens incompatibility being the cause of
    my problems, or could it be something else?
    (I don't think it's a contact problem, because I've only changed lenses
    2 times or so and never touched the electrical contacts).

    Then disregard my post.
    I would call that number listed in the FAQ link I posted and talk to
    Sigma about this issue. Especially if the lens is under warranty.

    It could be a defective lens, it's hard to say at this point.

    Good ole fashion defectivity hasn't been ruled out yet.

    Call Sigma tech support.

    I'd probably also take the lense to a camera store and try it on other
    EOS digital bodies to rule out a possible problem with the body.
    However, I think you said it works fine with other lenses you have?

    I think that you are ignoring the usual use of the term "compatible" as used
    for technological items and anything with microprocessors in particular. It
    is orthogonal with "consistent behaviour" and anything less than guaranteed
    1005 compatibility means "works some of the time" with "some combinations of
    settings and/or features". It's a fun world, if you don't weaken...

  19. Hiya.

    I _think_ that Sigma chart is concerned only with the image circle projected
    by the lens, not the whole lens - camera interface.

    BTW - when I asked Sigma about re-chiping a lens, the charge was nominal if
    I had the receipt but somewhat more if I did not have ther receipt. I think
    the charges were around £5 and £40 recpectively.
