Canon has been making cameras for quite some time now. The company has put out legendary DSLRs like the 1DX and is now competing in the mirrorless camera space with excellent cameras like the R5. 

However, as good as their cameras may be, they aren’t immune to damage. In this article, we’re going to take a look at Canon Error 20.

What is Canon Error 20?

The Error 20 is most likely to pop up on a DSLR as mechanical shutters are likely to fail at some point in time in a camera’s lifetime. The shutter is a rather delicate and precise part of a camera that has to work perfectly every time the shutter button is clicked to get that shot. 

There’s no telling how long a camera shutter will last. On consumer-grade cameras like the 1500D or the 200D, you might be able to get something like 1,00,000 photos before the shutter fails. Professional-grade cameras might even go as high as 5,00,000 exposures before the shutter says goodbye. 

However, in practice, even a basic camera like the 1300D might last you a lifetime. 

How to fix Canon Error 20?

Shutter failure is indicated by either the shutter blades showing up in your pictures or you might see the error 20 pop up on your camera’s LCD. Either way, the best thing to do in such a situation is to send your camera to Canon for repair.

The cost of repair largely depends on the camera you own, more expensive, professional-grade cameras would cost more to repair as compared to entry-level DSLRs, however, you can expect the repair to set you back $200-$300. 

Most Canon errors suggest the same steps for troubleshooting.

The error screen does suggest you restart the camera or re-insert the battery but unless the error is a false alarm, these things aren’t going to help you much. 

According to the Canon Knowledge Base, the Error 20 (listed as Err 20) indicates a mechanical malfunction. Canon suggests the following solutions. 

  • Restart the camera.
  • Reinsert the battery.
  • Use a Canon lens.
  • Contact your nearest Canon Service Center.
