Error 5 with canon eos rebel 6.3 mp

SOURCE: Error 99 only when flash pops up

We ended up sending the camera in to Canon. $200 unless they find something more wrong. Luckily we have my Nikon D80 still. I will say that Canon replied via e-mail fairly quickly and one paid, said 7-10 business days for the repair.

In the communications option of the camera Menu, there are two options to choose from. Try changing the options. one of them works with Canon software to download images.

The problem is in the flash pop up switch. It is probably jammed in or there is some kind of substance on it causing it to stick. You can find it by manually popping up your flash. You should then see a little black spring loaded post on the release button side of the flash. Check to see that it is not stuck in in any way. If so that is why you are getting error 5. To repair you can try a qtip an a little rubbing alcohol. Otherwise you will need a technician to do it.

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.

SOURCE: Canon rebel xt eos shows ERR CF. What do I do now?

Check that the pins in the camera that connect to the CF card are clean and not bent. You will probably need a good light and a magnifying glass to see into the card slot. If you can see a pin that is bent you could try straigtening it. BEWARE- turn off camera and use a non conducting "stick" ie cocktail or toothpick. Not sure for a Canon but a colleague paid £40 for a new pin assembly for a Nikon with similar problem.
Hope this helps.
