The Panasonic GH5's sensor is suspended in a magnetic field when in use, allowing it to move on 5-axis to stabilise the image.
However when not in use it is completely loose and flops around in its space (it can move around by a good 3-4mm in all directions) and it can clearly be heard and felt knocking around, presumably it has some sort of rubber buffers around it.
However in the long term, being carried in a camera bag, rucksack, handbag, neck-strap etc etc... Is it likely to suffer any actual physical damage? Is the flexible cable to it likely to degrade in time?
I am fully aware that they are built like this, and have of course been thoroughly tested, but sometimes there are unforeseen issues later in the life of products.
