My 5D seems to be dead...

  1. I was doing some shooting with my 5D, testing the Zeiss 50/2 Makro Planar lens. I was doing some long exposures, the frequency of which is nothing I haven't done before. I finished shooting and turned off the camera to change the lens to the Zeiss 50/1.4. When I tried to turn the 5D back on, it wouldn't turn on. The battery that I was using had only one power cell left, but I did have another with me that I checked before I went out and it was fully charged. I changed batteries, but it still wouldn't turn on. One of my friends suggested that the sensor overheated from the long exposures and to let it cool down for a few hours. That was three hours ago and it still won't turn on.
    Any ideas?
  2. Probably fried something important and Canon Service will need to RR a board. The 5D is hitting on 6 years old so you might, as a desperate last ditch before CS, and change the backup/PRAM battery. They typically last 4 or 5 years. A dead or failing one has been known to cause some funky *X&$#**X&$#**X&$#**X&$#* to go down....
  3. I would send it in. It could be a board or it could be something as simple as a bad power switch (which shouldn't be that expensive to fix).
  4. I took it to Unique Photo this morning and one of the techs told me he's heard of five cases or so of the 5D not being able to handle the circuits or whatever on the Zeiss ZE 50/1.4 and thus getting fried...
  5. I'm really sorry to hear of the problem with your 5D. I hope you manage to arrange a fix at a reasonable cost. For the benefit of other owners of the same model, it would be very helpful to let us know how it turns out. Good luck.
  6. Thank for all the responses, guys. For the weekend, I ended up renting a 5D Mark II. It is pretty sweet. I especially like the video. I have a Sony HXR-NX5U, but you can't beat the depth of field that lenses meant for still photography can produce. Then again, the video off the Sony runs at nearly 4x the bitrate of the 5D Mark II.
  7. You could have ended up discharging the internal battery that keeps the clock (amongst other things) working. You may be able to get this back enough to operate the camera by putting in a fully charged battery and letting the camera sit for a bit (try overnight or a couple of days). I think I had this happen to one of my 5Ds when I had it sit too long with a discharged battery in the body.
