After just two weeks my new 80D has developed a serious error. I'm sending this one back. I really like the camera but I don't want a problem that keeps coming back. Should I worry about getting another 80D?

I've had an 80D for 2.5 years and have never had an Error 20. In the last few months I've had an occasional Error 30 (evidently a shutter issue) but have put it down to extreme humidity (I live in the tropics and it was wet season) because if I left it under a ceiling fan for a while it would work fine. The air's drier now and I've had no issue. Great camera.

No issues with my 80D (nor my 60D) although it hasn't had a lot of use.

Canon says the following:

Err 20
Description: A malfunction with the mechanical mechanism has been detected.

Resolution: Turn the power off, then remove and re-install the battery. Then turn the power on again.

Some people report however that they have to leave the battery out for an extended period ("overnight"). In some of the Canon cameras people also said that after removing the battery, turn the camera ON and then hold down the shutter button for about a minute. This would supposedly bleed off any power in the camera circuitry. Then switch the power to OFF, reinstall the battery and then retest.

Certainly if it happens again, I would get the body back to Canon. Don't push your luck and run out of warranty. If you can, enclose a photo of the back screen error message when you return it.

I've left the battery out for a while trying this fix. It really shouldn't happen at all though. Again I've only had this camera a couple of weeks. I'm returning it to the retailer. I'd like to get another one but I'm hesitant until I learn if this problem is common and if I can get it fixed at all.

BTW I was not in a humid situation. I had been using the camera with a longer lens than I had been using. I shot several photos with that lens and laid the camera down (on the couch next to me so no impact issues) and when I picked it back up again maybe an hour later it had the error message. I'll shoot a photo of the back screen with another camera if I still have the issue after I put the battery back in. I'll post it here.

I doubt this issue would be considered “common”. When I bought my 80D about 2 years ago, I researched it quite extensively and I don’t remember finding any “common” issues. What few complaints I found, when you drilled down the blog, it was usually operator error. These cameras can be quite intimidating, especially if you’ve come from a point & shoot or Smartphone device.

Keep in mind as well, when you search forums, blogs, etc you tend to see the complaints, not the praise!

I've had the 80d for almost two years and I haven't had any problem.

First I'm a long way from being new to cameras of all kinds. I started doing serious photography with a twin lens reflex camera. Nothing was automatic in those days.

I didn't find any user error that led to the Error 20 situation. And I found more than a few references to it and some stories about what it took to get a camera repaired out of warranty. I just didn't want to buy a camera with a known issue. I know we see the complaints on forums but it still indicates someone was having the problem.

I'm just asking if the problem is common.

I don't think it is a common problem. I have had an 80D for about 1.5yrs and 7500 shutter snaps (7D2 is main body) and have never seen an error. My 80D was picked up as a refurb directly from Canon.

If it happens again, I would exchange it. If you are uncomfortable with it, by all means exchange it.

At this point it only makes sense to return this particular camera. It's that or send it back to Canon for repairs. I can have a different camera here in a few days. It will almost certainly take considerably longer dealing with Canon. Since this particular example of the camera failed after 2 weeks I wouldn't have much faith in it lasting. I will try another example and hope for the best. I've owned quite a few Canon cameras and this is the first time I've had a problem.

Error 20 is related to a mechanical problem which can be either shutter, mirror or aperture control so you must also consider that it may not be a fault in the camera and the lens may have a problem.
As you were using a different lens to that which you normally use then it may be worth making further tests before you return the camera.

I tried the first lens again and it would not work.

I agree that this is not common issue with the 80D.
As someone that has owned, operated, and modified nearly every Canon DSLR model, the error 20 is definitely a shutter issue.
If the individual shutter leaf(s) do not return to exactly the correct position this error will come up. If the shutter has any resistance in movement it will come up. If the mirror does not return to position it will come up, too. Or if any of the sensors that report these positions go bad... though I have to see that in person.
I have also seen it related to a lens issue as well. But much less common.
What lens were you shooting with when the error happened?

I would return it and try the next one. Even if it doesn't happen again you will be worrying and thinking about it.
I love my 80D. It will be with me for many more years to come. And then will get handed down to my kids or extended family before I sell it.
It's that good (or more accurately so much camera and image quality for the $, obviously good is subjective and there are better cameras out there for X and Y reasons).

Get the replacement and have fun. Dont look back just keep shooting.
Good luck

Was the camera already in the error state?
Did you cycle the power(or remove battery) between changing lenses?

I was using the EF-S 55-250mm that I've had several years. I actually used it a couple of hours and then set the camera down for another hour or so. When I picked it back up that's when I got the error. I've used that lens many times in the time I've owned it. It's never been a problem before.

I didn't disconnect the battery while changing lenses. I did have the power off. I've never heard that the battery should be removed. In any case the lens worked for a couple of hours at least.

I've already made plans to get another camera. I'm back to being torn between the 80D and 7DMkII. I'll probably get another 80D.

When this happened, had you been doing any shooting in LiveView? I did notice that for some people reporting this error, actually various cameras, there is some common talk about LiveView and when exiting LiveView the mirror doesn’t fully return. In some instances people found that mounting a different lens (I see you have the 18-55) and cycling through LiveView cleared the issue.

By the way, can you repeat the issue “at will”?
