don't take this as the expert answer.. but isn't this the same for any camera.. Look at the file size between the iso 640 and the iso 51200 for the first clue.. frame rate always slows down on all the cameras i have when higher iso ..so my answer without being technical is........what your seeing is normal
It's the best answer I have yet so I'll go with it.
That said, those responding on other forums cannot replicate the issue.
