FYI - there is a new firmware that was released November 7 that improves image quality (no tangible results to report). Just know that if you update the firmware, it will appear you did not, because the reflected firmware version will show as a different number - 220.127.116.11 instead of 18.104.22.168, which is the updated firmware version indicated on the documentation. Germany is aware of this.
Interestingly, one of our clients ordered this lens about 6 weeks ago from CI and received it in less than 2 weeks. Don't know if the current situation reflects that or a longer delivery time.
Just experienced this as I updated my 30-90. Do I in fact have the new firmware installed even though the version number is wrong?
