Error 99 only when flash pops up

Canon EOS digital rebel XT. Canon EFS 18-55 lens.
Camera takes non-flash pictures fine.
When flash pops up, regardless of mode, screen shows "busy" then err 99.
I have cleaned lens contacts with pencil eraser, removed battery for two hours to reset, reset to default via menus, tried without CF. Any time the built-in flash pops up, the same error. I even tried it with the lens off - same result.

    Me too! I have the problem with both the stock lens AND a Canon 50mm lens... I guess the only thing to do is send it back, but with Christmas a couple weeks away, I'd hate not to have my camera. That's kind of disappointing....

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.

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.

We have a Canon rebel XT EOS the flash pops up no matter what the

Frustrating I am sure. I had the same problem on my first XTi. I cannot remember what the settings were, but I think I was set for portrait and had flash set as the white balance default source. Therefore the camera always popped up the flash assuming that I wanted or needed fill flash.

Change you white balance to sun/shade/tungston etc as is appropriate, choose a faster ISO speed in lower light levels and try using the P or Tv mode and use a shutter speed that generates a middle range aperature for your particular lens.

Err 99 shows up on screen when I try to take a photo

This is usually a lens error. Take the lens off and clean the contacts on the camera body and lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

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.

Wanting to use add on flash

The "error 99" is a general error on Canon cameras meaning "something's gone wrong and I don't know what to do about it". If you get them all the time, the camera is effectively dead and must go back to Canon for a service repair (circa £175 if I remember correctly).

If the error 99 only happens when you try to pop up the flash, but otherwise the camera can take good pictures, then yes, an external flash unit could well solve your problem. With an external flash on the hot-shoe, the internal flash is completely bypassed and the camera will never try to pop it up.

I recommend taking your camera to a shop such as Jessops and ask to try out a flash gun to be sure.
