My 70D turns off after 30 minutes in live view and I can't do anything about it. I turned off Auto Power Off feature, but it still does it. Any other tips, please?
It's explained on page 217 of the manual - seems like Live View shooting will stop after 30 minutes no matter what (it is said that the display turns off without saying anything about the sensor, but most probably the sensor itself turns off too).
I guess it's a safety measure to prevent damage from overheating to the sensor and to save battery.
