OM-D How to make focus area small
Yes this works & on the EM5 you're right you can use the wheel to go to the smallest focus size in magnify view which is 14X. When you turn off & on the camera you hit the magnify button & it will use the smaller focus area w/o actually magnifying the screen if you don't want to. Would be nice if the next EM5 firmware update bypasses this but it's not too bad as it is either.
