Receiving multiple error codes definitely indicates that your camera should be taken in for service. Unfortunately, there is nothing you can do on your end in terms of troubleshooting or fixing a range of error codes. The camera needs to be sent in for service.

Hello I have a 30d with a Canon 24 - 105 L series, USM, IS lenses attached. This system has given trouble free service for the past 3 years. It has done about 25,000 exposures. In the last 2 weeks it...


If you have done all that was listed in your description "normally" error 99 is an electronic malfunction however, a camera firmware update may also fix the problem. Canon has these updates on their site and it can prove beneficial in this case. One of the offices I look after had two Canon 30D's great camera and they used them hard for two and a half year and at 80,000 frames I had Canon Canada replace the shutter and shutter button which is a weak link in the electronic chain. The shutter release button gets oils from the users hands down into the circuit and causes faults as well. Most times you can see a slight build up of oils in the switch between the button and the camera body. Don't bother trying to clean it the stuff is already down inside. Try the firmware update first then if the problem is solved you are good to go if not then it's service time.

ERR 99 DURING SHOOTING


Hello :

The Canon Error 99 is a message that pops up when there is a contact issue between a lens and the body of the camera. Also it represents a bad battery, defective storage card and anything else the software doesn’t seem to like. It’s basically a catch all error message a bit like the familiar windows BSOD.
Up till now the current procedure to get rid of the Canon Error 99 was to take the battery out and put it back in. Canon have now created firmware numbered 1.0.3 that aims to tackle the Err99 message .



Firmware 1.0.3 fixes Canon Error 99 1. Corrects a phenomenon in which an image becomes overexposed when C.Fn.II-3 Highlight tone priority is set to “1′ together with other camera settings. (This correction has already been incorporated in the Version 1.0.2 and later firmware.
2. Corrects a rare phenomenon in which “busy” blinks on the camera’s display panel and the shutter cannot be released due to the timing of battery installation.
3. Corrects a rare phenomenon in which “Err 99′ appears on the camera’s display panel and LCD monitor and the shutter cannot be released due to the timing of pressing the shutter button.

You can download this update from this link : Firmware 1.0.3

good luck .

Canon 400d err99 message when trying to take a picture. how do I resolve problem?


Error 99 also refers to communication problems between lens and camera, so worth cleaning the contacts...you can't lose anything in doing so.
1. Take your battery out and reinsert it - this will clear it.
2. Clean your lens contacts carefully with a plastic pencil eraser. Sometimes corroded contacts can cause errors like this.
3. Try the camera with different lenses - if it is occuring with several lenses, it may point more strongly to a camera fault.
4. Make sure you have the latest firmware installed.

err99 is a generic error code that the camera cannot identify to a particular component.

One thing to try is to switch off, remove the lens and clean the gold contacts on the camera and lens.

This is a common cause for err99 and in a lot of cases cures the problem

Rebel XS ERR99


This is something I found when googling your problem.

Thank you for contacting Canon product support. I'm sorry to hear that
your EOS 10D is displaying an "ERR 99" message.

To isolate the cause of the issue, we suggest that you 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 a fully charged battery, and turn on the camera.

Does the "ERR 99" message appear? If it does, then the camera should
be serviced. If it does not, then please proceed to the next set of
steps:

1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.

Does the "ERR 99" message appear? If so, then the CF card is the most
likely source of the issue. Try using a different card.

If the message does not appear, please complete the following steps:

1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser
or soft cloth. Be careful that you do not let any debris fall into the
camera body.
3. Reattach your lens.
4. Turn on the camera.

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 should be serviced.

Keep getting ERR99 when i take my first shot after switching on.


ERR99 means the camera is not communicating with the lens - probably just dirty contacts.

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.

Err 99


This probably isn't it, but just to be sure... Make sure you have the latest firmware loaded. I was getting constant Err99's with my 10D and a new Lexar 40x card until I loaded the latest firmware, even though the firmware notes mentioned nothing about addressing CF card issues. Now everything is fine.
