Choosing your EOS camera controls to lock avoids you accidentally nudging dials and changing your settings while you’re shooting
BRIAN SAYS… Most cameras that have a lock switch or lock button also enable you to determine what is locked when the lock is active. Your EOS R6 Mark II is no exception to this; you need to locate the Multi-Function Lock setting in the setup menus to configure it for your needs. The default is that the quick control on the rear of the camera, the quick control dial on the top, joystick and RF lens control rings are locked on your camera. The custom settings offer the additional choice to lock the main dial and the touchscreen. If you find that you move the AF point with your nose, you could lock the touchscreen to prevent this happening.
