The X-M1 does not come with a EVF (electronic view finder). In the interest of saving a lot of battery power I am hoping to use an external viewfinder as an alternative to the absent EVF. This is only going to save power if one is able to switch-off the live-view display (or at least dim the backlight to nearly being black).
Is there a way of disabling, or severely dimming the X-M1 screen?
