At the Sony support website, I noticed that a firmware update is available for the SEL24f18z lens to enable it for full compatibility with cameras that have hybrid AF. Maybe it's been out for awhile, but I had never noticed it before. Anyway, can anyone confirm that if you do upgrade the firmware on the lens, then it will no longer be compatible with the Nex-7? I couldn't find that statement in the instructions, but I got the impression that if upgraded, it can no longer be used on both the A6000 and the Nex-7. Am I missing something?
