Canon EOS 40D - err. 99 while taking photos

I have a problem with my camera - Canon EOS 40D. The camera is relatively new, I bought it in May. Very often, when I take a photo, the LCD displays a massage: " Error 99. Shooting is not possible. Turn the power switch to and again or re-install the battery". Then I follow the instructions, but the problem tends to repeat. What is interesting, my Canon sometimes takes photos and in such a case, it seems everything is all right.

I use a lens EF 17 - 40mm L series. I have changed the lense and tried taking photos with other lense, which I borrowed from a friend, but it didn't solvbe the problem.

I don't know what to do. In my city there is no authorized Canon service.

I heard from one photographer that it might be a problem with the Software installed on my camera. Where can I download software for the camera and how can i upgrade it i my device?

Thank you for your help

    I had same problem. I sent it to Canon (also purchased mine in May). Canon stated it was the mirror and they had to replace it. Waiting for it to be returned. Send to Canon while it is still under the year warranty.

My canon 30D comes up with err 99 pleas help


My first stab at guessing would be the older-style lens can't communicate to the 40D, resulting in a read error. Any problem when using other newer lenses?

Try doing a full format of the card using the camera - don't just delete all images. Then re-zero the shot count. See if that helps.

Error code 99 on a 40D?


Welcome to Fixya
Err 99 could mean 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.

My Canon 40D suddenly came down with the dreaded Error 99 for no apparent reason. I have tried all the usual, battery, memory card, lens, but no luck. Even on the bulb setting the shutter won't stay open....

Canon 40d error 99


Try the following diagnosis steps: -

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.
