Don't worry, that's correct - the update file should have exactly the same name regardless of version. For better or worse, this is how the camera recognises that it's the right file for that model.

If you don't need KAF4 lens compatibility, there's no real need to update. That said, the update may include general stability tweaks, so - even if you don't need the added lens compatibility - you might still want to install the new version. It's up to you

Thanks for that
