It’s quite common for Canon DSLR cameras to get an “Error 99” message. Some say it’s a memory card error, others say it’s related to the camera battery. The truth is that it could be one of two or several other problems that could be related to either the camera body or the lens.

Here are some tips to help you diagnose error 99. These tips assume that you have already tried a different lens (from the camera manufacturer) and a different CF card (freshly formatted).

What causes Err 99 on Canon

ERR99 is a common error, but often the cause of the error is lens-related. This can happen for a variety of reasons. For example, if the aperture block on your lens is broken and needs to be replaced, the camera will tell the lens to change the aperture, but the lens cannot do so because the aperture block is not working, so the camera has no confirmation that the lens has executed its command. The result? Error 99.

How to fix error 99 on Canon

Troubleshooting the camera

First, we will check and isolate the problem. To do this, we will remove some components from the camera and test them without them. This will determine the source of the problem. To do this:

1. Remove the battery, memory card, and lens from the camera.
2. Completely turn off the camera for 20 minutes.
3. Put the battery back in the camera and hold down the shutter button.
4. If an error message appears, the problem is with the camera hardware.
5. If the error message does not return, insert the card into the camera, then press and hold the shutter button.
6. If the error message returns, the problem is due to a damaged SD card and you need to replace it.
7. If the error message does not appear, lock the lens and press the shutter button.
8. If an error message appears, clean the contact area between the lens and the camera body.
9. Take an eraser and clean these areas, taking care not to allow any residue to get into the lens holder.
10. Replace the lens and press the shutter button.
11. Check if the problem persists.

Troubleshooting your memory card

There are actually many ways to corrupt the memory card that are sure to cause problems with the camera. The best way to rule out this problem is to get a new memory card and insert it into the camera to see if the problem persists after rebooting. If that’s not possible, at least try using a different card to make sure it’s not a defective card.

Then, make sure you don’t do anything that might cause errors in the memory card database when importing photos. Insert the memory card into the camera and perform a full reformat. Don’t just delete photos, go to the menu and look for “format card”. If the camera can’t format the card, the problem is probably with the card.

Checking the Shutter

If you are unable to solve the problem using the above method, you will either have to take the camera to a service center or check some things yourself. However, this is not a simple process, and a simple mistake can ruin your camera forever.

1. Remove the lens and look inside the camera.
2. Make sure nothing is blocking the shutter button, and make sure it is fully in place.
3. Remove the debris, put the lens back in place, and check to see if the problem persists.
