Finally got my E-M5 and have been working to get familiar with the controls. I generally use center spot focus and would like to set a control to minimize the focus area. I set the movie mode button to the icon that has a relatively big fish and 3 relatively small fish. My sense is that this is switching between a relatively large area and a smaller focus area. Am I correct and if not, how can I set a function key to give me the smallest possible center area focus point? Thanks.
