How good would the experience be with a linux phone and an external camera?
I’ve got a pixel 6 and although camera’s are getting better each year, it’s not even close to a dslm. And video qualit is probably better with a proper action camera.
I mean, directly “mounting” the camera to the phone and shooting with the phone.
the general Idea I am getting from this would be something where the phone itself could be swapped out
Most nice modern cameras have either USB, bluetooth, or even wifi connectivity to connect to whatever you want. You could just have a normal phone and a normal camera and just copy the files off via whatever method you prefer.
