I have a Cannon Rebel XTI and i keep getting err 99

The battery is fully charged, i took it out and put it in many times and i still get the same error. I even bought a new memory card thinking it was that. It said to format it and tried that and thats when i got the error 99 and i'm not sure why it's doing this all of a sudden!

    I'm having the same problem with my camera as well, only I've tried removing the lens .. my issue is not being able to take pictures .. when I remove the lens I am able to take pictures, but when I put the lens back on it doesn't take pictures.  So I'm assuming there's something wrong with my lens.

Make sure your firmware is up to date. The current version is 1.09 which did address a problem with live view that could cause error 99.
Here's the link http://web.canon.jp/imaging/eosd/firm-e/eosdigital4/firmware.html


Also try removing your lens and putting it back on. Sometimes it is a bad connections between the body and lens that can cause this error.

Canon 400D,Error 99 keeps coming up,have replaced battery pack,even recharged batteries,stillbeing told to"replced battery pack".Help...


Welcome to Fixya
Err 99 could means several different things, such as... Memory Card, Lens or Lens contacts....

Here's what you can try:

Remove the memory card an enable "shooting with out memory card" and see if you still get the error. If it works your memory card is bad. Try another lens if you can. Clean the lens contacts with a pencil eraser (be careful not to get eraser dust in the camera body or in the lens). Worst case scenario is, Err 99 could be related to the shutter failing which would mean a trip to Canon.

Have a good one!

My canon eos rebel xti keeps showing error code 99



To isolate the cause of the issue, we suggest that you 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 a fully charged battery, and turn on the camera.

Does the "ERR 99" message appear? If it does, then the camera should
be serviced. If it does not, 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.

Does the "ERR 99" message appear? If so, then the CF card is the most
likely source of the issue. Try using a different card.

If the message does not appear, please complete the following steps:

1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser
or soft cloth. Be careful that you do not let any debris fall into the
camera body.
3. Reattach your lens.
4. Turn on the camera.

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 should be serviced.

Err 99 usually means your lens contacts are dirty either on the lens itself or on the camera.

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.

Canon Rebel Xt EOS Err 99


Error 99 is a "catch all" error that has several causes. It could be that your battery is not fully charged, especially if it is a generic, non-Canon battery. Charge for at least over night even if the charger says it's full. If that's not the cause, switches inside the camera will have to be cleaned by a repair shop.
