camera locks when disengaging mirror up

Issue #125 on hold
Former user created an issue

Have experimented with dropping the mirror as a method of saving battery while shooting with ML (since the LCD turns off). It works a few times at first, but will eventually lock the camera up (the lcd goes dead, and none of the buttons work). Reboot doesn't help - get "err" code on the camera's top lcd. Before ML, I would just plug in a mini plug into the AV jack to override the lcd and save batteries without having to power the camera down. That obviously won't work with ML since the AV jack is now a headphone jack. Once camera locks up removing the battery/interrupting the power supply (if using the AC adapter) resets everything and shooting is then resumed.

    I have experienced this as well. If the camera is left in non-LiveView mode for more than a few seconds it seems that ML messes something up.

    I believe this could be power related: I know that the (my) 50D has MLU release issues whenever the power is low; It seems to use a fair bit of power to release the mirror again. Replacing battery drops mirror... -Did you notice whether the occurrences you had were traceable to battery power?
