The ERR99 message reads shooting is not possible. Turn the power switch to off and on again or re-install the battery.If i open the battery door and close it again the camera will work fine but if i turn it off i will get the same problem again. Is this a setting problem or has something gone wrong with the camera
ERR99 means the camera is not communicating with the lens - probably just dirty contacts.
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 20 minutes.
4. Insert only 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 so, the camera may be faulty and requires a service. If it does not, then: -
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.
Does the “ERR 99" message appear? If so, then the CF card is faulty. Try a different card. If the message does not appear: -
1. Turn off the camera.
2. Clean the gold contacts on the lens by GENTLY rubbing them with a pencil eraser or soft cloth. Keeping the camera face pointing down, also clean the gold contacts on the camera, being careful that you do not let any debris fall into the camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.
If the “ERR 99" message only appears when one particular lens is attached, then that lens should be examined by a service technician.
If you see the “ERR 99" with a different Canon lens attached, then the camera is faulty and should be serviced.

For you to have a very good idea what the problem is. do this first
1. Format the card.
2. Take several pictures after formatting
3. Turn the camera off-on.
4. Take your first shot.
5. Take note of the number
6. Turn it off again.
7. Turn it on again.
8. Take a Shot. and this time it will display the Err 99
A work around here is when you turn off-on the camera, delete the first shot (the number at step 5) and it should continue shooting.
however if you turn it off and on again. the same shi+ happens all over again
in adition...
change any settings in your camera. turn off again. when you turn it on, you will notice you will still have the same settings.
My best guess to fix this problem is to remove and reinstall the internal battery. They said this will reset all setting in the camera...
I haven't tried this yet because it may compromise the terms in the warranty...
good luck
