A quick post to illustrate the different options for touch screen focusing on the EM1, also applicable for the EM10 as far as I know. There have been a very long discussion on dpreview between me and one of the forum members regarding this topic, and I have created this video to illustrate the options, and we seem to have reached a final conclusion at last.
The only thing not mentioned clearly in the video is the touch focusing mode, since there are 3 modes in stills mode and two during video recording, so here's a copy & paste from the original post:
When you enable touch screen in the EM1, you have three options:
- Turn touch screen off.
- Focus only, but not trigger the shutter.
- Focus and trigger the shutter at once.In video mode, there are only options 1 and 2.
