The error 99 is the scariest error on a Canon camera, and if you’ve never seen it yet you’re about to. Although Canon cameras aren’t more likely to make errors than other camera brands, they do have the notorious error 99, which you will need to fix before a wedding so you won’t be left without a camera.

Canon Camera Troubleshooting

There are a number of reasons why this occurs in a Canon camera. First, make sure that the battery is fully charged and inserted correctly. Even if the battery has been inserted correctly into a charger, it may not have been inserted properly. A charger might not have been properly plugged into an outlet, resulting in an uncharged battery.

Err 01 Canon 24-70

The shutter clicks, but the error message shows up on the back screen whenever I stop the lens down, rather than wide open at 2.8. It has happened to me both on a 1D X body and a 6D body; the former told me to clean the contacts, while the latter said to check the connection between the body and lens. I can sometimes get more stopped-down photos by wiping the pins off with a cloth before the error message returns.

Err 02 Canon

There is a possibility that your card may have gone south on you if you are getting error 02, but you can try reinserting it back in and reformatting it again. Please check the warranty period for the specific card you have.

What causes the “Err 99” on a Canon camera?

Err 05 Canon

A flash error 05 can occur when the flash is obstructed or simply won’t pop up when the camera tries to use it. By switching the [P] mode on the front of the camera, you can manually release the flash by pressing the [FLASH] button located just below the flash. You will have to replace the camera if you continue to see Err 05 and the flash does not release.

Err 11 Canon

A connection is dropped or the setup time out causes Err11 to appear when the camera cannot detect your device.

It is possible for your product to display an error code or message due to various reasons. Below is information that describes why your product shows an error code, as well as what you can do about it.

Lens contact deposits: In some cases, deposits can build up on the lens contact pads that interfere with the user’s ability to take pictures, causing this error.

Err 30 Canon

Err 30 indicates there is a problem with the power source. Please try resolving the problem using these steps:

Blocked shutters: In most cases, the error is due to problems with the camera’s shutter path. Sometimes debris can get into the camera and get stuck in the shutter path, which can interfere with shutter movement and cause this problem. The shutter path should be completely free so that it does not interfere with shutter movement.

Shutter Curtains: The shutter curtains may be preventing the shutter from closing and causing a malfunction. This may be due to wear and tear caused by time. It could also be the result of physical damage to the unit.

Canon Err 80

An error code 80 indicates a malfunction in the control system or images. The steps for trying to resolve the issue are detailed below.

Broken shutter material: If you remove the lens from the camera and look inside, you may see a soft shutter material. This material may be bent or displaced from its original position, preventing the shutter from closing and causing the defect. It is very important that this material is firmly in place and that the shutter closes properly.

Cameras need service if the error 99 continues to occur when using a different lens. Lenses need service only if the error 99 only appears when using the first lens.

Flash Card: In some cases, the card used to store images can cause this error. Sometimes the card can interfere with the camera interface and interfere with some system functions. This can cause the camera to stop working and display this error. It may also cause the user to be unable to connect the camera to the computer.
