My Canon 40D has an "error 99" when shutter button is pressed.
Here is the list of things I've tried:
- change the battery
- shoot without CF card
- shoot without lens
In all cases, the error comes back, systematically, and it is impossible to shoot again or do anything else (even picture preview mode doesn't work). A reboot is necessary, but the error comes back as soon as I try to shoot again.
I am aware of the other posts about this problem but it seems that in those cases the problem was the lens (see here).
(According to some readings on the web, I found that "error 99" can mean a lot of different stuff...)
Does anyone know how to solve this problem?
