hi...
before couple of days every thing was ok i toked some photos normally at night
when i waked up in the morning i found something very strange :
the camera can not auto-focusing correctly ... cannot recognize the auto-focus
i tried every thing you can imagine like changing the lens or reset even re-update the firmware
not focus nor shooting in auto-focus mode when use viewfinder but it normally work when uses the LCD
in this video you will see whats going on with me ...
note: i don't know why the speed shutter & aperture blinking in auto mode !?

Leaving the battery out won't reset anything. It just depowers the camera. When turned back on with a battery all the same settings are in place.
