I just only change from M to Auto Mode.
Y applied auto focus with half botton with the Canon 50 MM F1.4. And the image in the LCD stuck with the photo.
Turn off, the camera brick with power on, photo frezzed in the LCD, and message Err 70 on the small viewfinder, near buttons.
Reset battery, and again and again.
I change to other modes and no problem photo and video. Everything fine.
I never use this mode. It's not a problem for me.
I will try to format card, get the build again. Change to other Canon Lens. And test.
Formated Card, add the build again. Battery out for more than 10 secondos, works and no problem so far in Auto-Mode, photo and video.
Appear that this is the best way to go in all the possible problems.
