Use the product on a Pana FZ1000 - class! Somewhat stiff and rigid - what I see as an advantage, robust material. The first time a bit 'Oregami', but once finished folded not rocket science. The additional screen can dranstecken, or let it remain. It is mounted with three Velcro patches, and -i held by the existing straps with buckle closures wind resistant.
Unfolded about A4 size and a few mm thick, fits into any camera bag.
