And I finally got round to replacing the dodgy lens in my new Mobius with the ok lens from the old camera. It was a bit fiddly, especially because the used the smallest screws known to man. Also the lenses don't seem to be the exact same size, but luckily the lens fit into my new camera, although now the old camera is a bit useless because I can't even close the case with the lens in lol. I might have to cut out some plastic to get the lens to fit.
But first I need to try and fix the problem with the lens itself, and I have a new sensor to fit into the lens. Has anyone opened a Mobius lens before?
