I added one more page to my tutorial how to use the Canon Connect app to control the Canon EOS camera. I found a way to disable the annoying behavier of the camera to do a auto focus on every photo it takes but still have the lens in auto focus mode.

You find the last on page 4.
I use this when I only have the tripod with me, photographing meteor showers etc.
