Canon Err 20 error. My experiences with canon and the repair

[@davemagnani5166]

I've been using Canon since 1976. I got a 40D in 2007, and then a little Rebel Xti for hiking, and then another 40D for a backup when doing events. I started using both 40Ds for events to keep from having to change lenses. Using 3 cameras, none of them had a lot of shutter actuations. The one time I went to a small event to shoot tethered to a laptop to immediately print the shots, I decided to leave the backup 40D home since I had to transport the laptop and 2 printers. The 40D shutter failed on the 3rd shot, and I had to use the Rebel that I kept in the car. I had to swap out the memory card to the laptop in order to print, since the Rebel doesn't have live view for tethering. It was a nightmare. I checked the 40D shutter count, and it was only a little over 8,000. Sent it to Canon, and they quoted me almost $300. I complained that it was rated for 100,000, but they said it was out of warranty. Now, my M50, that mostly sits on a tripod at the kitchen window for shooting birds, has a dead shutter. And it can't have anywhere near 100,000 actuations, and it is out of warranty. Two instances of something that should, according to Canon, have lasted much longer, warranty or not.

It might be a power issue. When I was in Turkey they had such bad electricity it didn't charge any devices properly. Canon is unkillable, err20 without physical faults is possible. It comes on with automatic shutter adjustments. It somehow messes things up.

I get this from time to time on my 1DX and have found that it usually clears up if I just pop the memory card door open, but it comes back again after a few shots. Then once it settles down, I can shoot thousands of frames until the next time...

Going through the same problem at the moment with my Canon 90d.Sent it to an authorised Canon repairer, Camera Exchange Colchester, on the 24th August for an estimate. Phoned a couple of times, still no estimate. A bit pissed off now !

Canon eos 5D mk2. Started after very cold snow work then rain. I have to stick it on a radiator to dry out with out the battery and she is normally ok.
