I have a 5d Mkii that keeps giving me a error 20. What is problem.
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. This is direct from Canon.
hello, it’s a late answer, err 20 corresponds mainly to the mechanism of the defective mirror. but the shutter may be defective, (although err 30 should be displayed), or the motherboard if the device displays err 20 after wetting the device (but this is unlikely). it can also be an electronic problem on the lower board when exposed to water.
I think it might be also a contact problem between your body and the lens. Check if the lens are properly attached to the body when you twist them into place. If you can slightly move it, take it off and tighten the small screws at the bottom of the lens that holds the EF mount to yhe tube of the lens. Now try to reattach the lens and test if the problem still exists.
Hej Jag får fel meddelande err 20 när jag går ut och fotograferar och det är kallt som det var idag, minus 3 grader. Men när jag kommer in och kameran blivit varm fungerar den normalt. Jag köpte helt nytt Canon original batteri och laddade den fullt innan jag gick ut. Kan de möjligtvis vara fukt i kameran . Mvh Jan
