I have had the same idea, and I bought the following adapter (see attached) but I cant remember or find where I bought it from. But found something similar on ultimateaddons.co.uk -
I never got around to fitting mine because there isn't a flat enough surface on the inside of the screen on my then FZS1000, or now my FZ1 or GSf1250. That and the mount in the attached images dosent stick out far enough away from the screen to have the phone in a vertical position. But here are 2 issue with that -
- I need a different mount that has a bigger gap from the mount point to the phone
- Polycarbonate can be drilled but has to be done carefully so as not to crack it, you could I think melt holes with a soldering iron and trim away excess around the holes. But I don't know what if any stress's it would set up in the polycarbonate material.
