Sony cameras and .RSV files

Which Sony cameras leave .RSV files behind, and how to get the footage back.

Sony cameras that record XAVC S, XAVC HS or XAVC S-I to an .MP4 write a temporary .RSV file while recording. If recording ends without a proper stop, that .RSV is left on the card. RSV Rescue rebuilds these from the .RSV alone, with no reference clip.
