Check the pins in the memory card slot. It sounds like a pin is bent causing a short.

Hi,

Please look inside your cardholder and you have seen a lot of small pins.
If one or more of the pins are bending or missing it gives an error on the camera display

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.

Hi there, did you check the card itself? SD cards have a locking switch on the side. Move the switch from locked to unlocked. Put it back in the camera and see if that helps.

Can you read the card in your camera?
If you cannot read the card in the camera...wow and ouch.
Try to get the card to a friend or someone who can read the CF.
Then see if they can read the card.

Hate to say it, but with an error like that, it may mean that the CF card is not working.

Are you trying to read the CF card on a reader on the computer?
Try your usb cable to the computer instead of the reader.

It is possible that the driver has become corrupted for the reader on the computer. Try the above, see what happens.

TRy and reformat the CF card through the camera. Youll lose the pics for sure but you cant see them anyway. You can also check for bent pins in the CF slot. Sometimes if you shut down the camera in mid write to the card, itll mess up the cards FAT (file directory)
