The Canon 20 D is a fantastic camera but the weak point is the shutter it last about 70 to 80,000 actuation then causes a bunch of problems. In Canada it cost about $180.00 including the shipping to the repair depot to get it fixed.

Hi LLFraserny,
You can probably try to isolate the error 99 first.
To isolate the cause of the issue, do the following:
1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 30 minutes.
4. Insert a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If it does, then the camera will need to be serviced. If the message does not appear, then please proceed to the next set of steps:
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.

One last item to check before sending camera to Canon service is the alignment of the shutter. Life the mirror and visually inspect the shutter curtain. If each segment is not completely straight, touch it lightly with your blower bristles and try to pop it back into alignment.

Hope this helps,

Hello - I figured it out. I had the exact same problem. The shutter failed and it had to be fixed by Canon. Apparently that happens after the shutter fires so many times (like a click-count on a printer). I just got my camera back and it's doing awesome now.

If two cameras are doing it, I would suggest the contacts on your lens are dirty.

If the camera doesn't turn on after this, even without CF card and lens attached, then it needs to go to a Canon service centre. Don't tell them you got it wet, and maybe it will get repaired FOC.

I get error 99 sometimes on my 20 D but it?s usually to do with a lens that is attached. Sigma lens have been known to cause error's. If it's not that or dirty contact on the lens then it could be a more serious problem. I would at least check it out with a canon dealer/repair centre.
