Warning. This might be a really stupid question. On the OMD and many other OLY cameras. There is a touchscreen option for Touch to FOCUS, which does not release the shutter. What is the point of that option? Maybe someone can help me use its function... Is it only for video? Because when i use it, then press the shutter release, it refocuses anyways. which is defeats the first action. Because if I didnt want to use it, I would select the First Function which is NO TOUCHSCREEN FUNCTIONALITY. If I wanted to actually take the picture, I would selct the third option, and make it release the shutter when pressed..
