I am getting this error message Shooting is not possible due to an error I need help please.
Hi! The following text has been quoted from the Canon forums, someone had a similar issue and this is what the rep answered: “Err 30” indicates that malfunctions related to the power source have been detected. Please follow these steps to attempt to resolve the issue: Remove the battery from the camera. Using a soft microfiber cleaning cloth, thoroughly clean any contacts that you are able to clean on the battery and inside the battery compartment. Do this even if the contacts already look clean. Retry the battery in the camera. If the error still occurs, please try an alternate battery. If the alternate battery produces the same results, your camera will require service to correct the issue." Hope this helps.
Also monitor its environment that could easily create this issue. Like leaving camera or any delicate device in hot/damp enclosed vehicle. They can be easily forgotten there, exposed for days. Good Luck.
