I'm starting out shooting some video with the e-m1, to put together some simple travel videos. My google-searching has failed to turn up popular settings, so I'm looking to see what people are using for settings for video settings. I shoot a lot of stills, and thumb-focus (ael/afl button) is how I've done it for years, so in a/s modes, I have that button set to focus. To shoot movies, I've been normally switching to S, setting to 50th (24 or 25 fps), and hitting the red-movie-record button. This leaves the focus button as the thumb. If I turn the dial to the movie-mode, then I can't seem to remap focus to the back button, and it's a 1/2 shutter press. Do I want to leave it in C-AF to be able to pan around? Or S-AF? It seems to adjust focus slowly if I pan from something close to far right now. And pushing the button adjust the focus quickly, but tends to hunt also, which is quite ugly if trying to shoot video. Any suggestions would be appreciated. FYI, using the 14-40 2.8 pro lens on the E-M1, nut also have the 17 1.8.
