Tip time: EOS 5D Mark III: Multi-function lock

If you find yourself regularly changing settings on the camera accidentally while moving around, then making use of the multi-function lock can avoid issues when you come to shoot in a fast-paced environment. The lock switch below the quick command dial can be used to lock the main dial, the multi-controller or the quick control dial – simply select which you would like to lock through the custom function in Group 2 Disp./Operation. When you come to change a setting, you may see L displayed in the viewfinder and on the top LCD panel. If this happens, you will be unable to change the setting because the multi-function lock is set. Simply flick the switch and the camera will return to normal.
