@bonemap bit off topic from GoPro but I have been using the newish pihq camera with c/cs lens mount https://www.raspberrypi.org/pr... with a raspberry pi to make hdmi cameras - very few lines of python code to get full screen hdmi out. There are pros and cons of course - lots of lens options, but fixed focus. Lots of camera options can be fiddled with in code. Not many more lines of code to make a time lapse camera, and very customisable.
