The Canon EOS 60D is a 18 MP DSLR (digital single-lens reflex) camera with an articulating LCD screen. The camera was released August 2010 and is identified by the EOS 60D printed on the front of the camera.
There are times that Error 20 shown up even though I remove and reinstall the battery or switching on/off the camera. I think that the Mirror is the problem here.
