The Err 99 problem occurs due to dirty contacts between the body and the lens. I recommend cleaning the contacts. You can then turn Off the camera and then remove and reinstall the batteries to reset the camera to get the problem fixed.

Canon 450D, ERROR 99 only when flash pops up


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.

Flash Problem


Hey tombston,
An error code of 99 is Canons general error code for this camera, and they suggest cleaning the lens contacts and/or removing the battery and then reinserting it. If this doesn’t work I would try resetting the camera to the default factory settings, and directions on how to do this are on page 35 of your camera manual. If this doesn't work I would have the camera looked at by an authorized service technician. I have included a link to a PDF download of the camera manual in case you need it. I hope this helps!

Rebel XT will not work with new faster CF cards.


Check the volume and speed of memcard, maybe it is not compatible. error 99 is an indication that a lens or shutter curtain is not working, so i cant see any connection with the memcard problem. Check your camera memcard compatibility.

Error 99 only when flash pops up


I know what you two are talking about. I ordered a Canon EOS 300d from a site called "Keh" and I had never used one before... so I get it in the mail on time. The camera works fine for a few minutes then I get an "error 99" and can't do jack with the camera. I researched online and even called keh ... I read and heard that it has to do with the lens... so I sen't the camera back and got my money.

Error 99


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.
