So following a recent trip overseas with my EM-1, every time I asked a passerby to take a photo for me, they had difficulty with my autofocus instructions. Everything is setup, and all they had to do is focus on me (Not the background!) and press the shutter. I even set a small aperture so when they inevitably focus on something else I can possibly salvage the photo as a low-res facebook snap. I've tried two methods, one is having centre zone autofocus enabled meaning they have to focus on me, then drag and frame the photo. However this proved too difficult for iPhone photographers. I then tried the screen-touch autofocus-and-shutter function on the EM-1, where you just frame the photo then touch the LCD where you want the focus and it takes the shot. "Just tap on my face, that's it." Very similar to smart phone photography, but again 4 out of 5 people were still bamboozled, resulting in me having to walk over and explain it again. I don't expect perfect framing and composition from a passerby but for god's sake it was like working with a special needs class the entire trip. How do you setup your camera so that a random can take a photo of you?
