It seems they choose a region to beta-test the firmware before going global. Just guessing
As for teleconverters, I didn't know there was an issue, so I grabbed my Tamron 1.4 TC to check it with my 300mm. It does hunt, but, it hunts with my K5 also and it's never shown up on my EXIF data. It may not be just a firmware issue but a TC issue. I'll have to wait to get the new firmware to see if there is a change. I'll let the Russians take it around the block a few times first
[edit: Looks like I was wrong about the beta-test:-)]
