    My EOS1d Mk4 has just developed a problem today with the shutter, when I switch it on it now fires off continuously, also the Menu and info are no longer showing on the back screen when it is switched on. I did get caught in a rain shower today, would that have anything to do with the problem. Also when switched on all buttons are unresponsive. Any help would be very much appreciated.

    Hi Dave,
    Your EOS1D Mk4 is, like all of the 1D series, weather sealed but the fact that your problem has occured after you were caught in the rain may be more than a coincidence. There may well have been some moisture ingress.
    My advice would be to refrain from switching it on again and to take it to your nearest Canon service centre or qualified technician.
    I hope that it is fixable.

    How much rain are we talking here? Did you try to cover it from direct rain? While weather sealed I am sure moisture can find its way in, it would be worth having some protection against the elements if rain is possible, even something as simple is a plastic bag or jacket to cover it. If the rain was light or you tried to shield it from the elements water should not be the issue. Maybe the shutter is stuck depressed.

    Lets assume for a second that it is water damage. Then I would immediately remove the battery, memory card, leave the lens on and place the body and battery in a bag of rice and seal it for a few days and hope that they suck out the moisture enough and your camera comes back to life. It would be a guess of mine that the water some how is shorting out the shutter button or something. If the camera does not work right next week, Ray is right shut it down immediately to stop excessive wear on the shutter and contact canon.

    The question I would pose is if Canon can't help you reset it and get it back to operational then do you send in an $1100 body for a very expensive repair or do you go shopping for something else?

    Thanks Ray and John, I think the problem was moisture ingress and was entirely my fault. I don't always take my large camera bag out with me and normally, as you rightly say John I would carry a plastic bag/small bin liner with me in my packet. Unfortunately not this time, lesson learnt! I am happy to say that after removing the battery and card and placing the camera near a radiator over night, it is with great relief now working again. once again many thanks to the both of you for your quick response.
    Kind Regards
    Dave

    Hi Dave, That is VERY good news and it must have been a huge relief when it sprung back to life.
    I can imagine how worried you must have been and, as you have said, it is a lesson well learned. Three of my four cameras are weather sealed/weather resistant but I choose not to put them to the test. I am a fair weather photographer! :D
    I look forward to seeing some images from your revived camera.
