What is the Canon Error 99?

Usually, most of Canon’s error codes point to a specific fault or failure in the camera. However, error 99 is more of a general failure error. 

It can be caused by lens failure (which is also the most likely cause)/ It could be a memory card failure, your lens contacts might be dirty, it can be a malfunctioning shutter and sometimes even a simple power cycle can fix the issue. 

However, if nothing else works, you’re going to have to send your Camera back to Canon and hope the repair isn’t too expensive. 


How to fix Canon Error 99?

Here are a few solutions you can try out to see if your camera comes back to life. 

Reboot the camera

The first thing you should do is restart the camera. This method can fix just about anything from a broken toy to an expensive computer or in this case, your dear camera. 


Check your lens

The most likely cause of this error is a mechanical issue in your lens. Check to make sure your lens is fine, that it has no damage and that the autofocus motors are working fine. Another thing to check is your aperture ring. You may even have to send back your lens for repairs.

Ensure your lens is in working condition.

Clean camera and lens contacts

Every photographer has seen the camera and lens contacts while swapping lenses. If these contacts get dirty, your camera might not be able to detect the lens correctly and hence throw this error. In such cases, try wiping off the contacts on the back of the lens and in front of the camera with a dry cloth (preferably microfiber) and see if that resolves your issue.

Do a power cycle

Your camera has two batteries inside. One of the main batteries that we’ve all seen and the second is inside the camera that powers low-power internals such as the clock inside the camera. 

To do a complete power cycle, you’re going to have to remove your battery and memory card, disassemble the camera, remove this battery as well, wait for five minutes and put everything back together again. Now, all that’s left to do is restart the camera and pray. 

Since this method requires disassembling your camera, we don’t suggest you follow it unless you’re comfortable tearing down electronics. A lot can go wrong which can up your repair bill into a whole new camera bill.


Check the memory card

It’s a long shot, but memory card issues can also trigger this error. Try inserting your SD card into a computer to check if it’s working properly and the system can read and write files off the card. You can also try another card in your camera and check if the error reappears. 


Send it to Canon

If all else fails, the best thing to do is send your camera back for repairs to Canon. It might be expensive, and it might take some time but that’s the best thing you can do for your camera and ensure its longevity.
