has anyone had a problem with a error 20 message on their 5DII. Showed up periodic about a month ago and this weekend came on for good. Body is relatively new and the camera does not get heavy use. batteries where fully charged. any insight appreciated.
I have about 20,000 actuation on my 5D MKII without seeing Error Code 20. I have seen Error Code 99 on one occasion, but I could have never have duplicated the circumstances (it involved really close lightning and thunder, don't ask!).
I don't know what error code 20 means in Canon speak. Error code 02 was used for bad CF cards.
