Just got home from Tokyo (so very tired)... No additional lens in my bag, maybe next time. I also found the time to drop into the Tak shop in Akihabara before I left, I asked my wife (who was in the store with me at the time) if she minded that I purchase the TOA-150 that was there
BTW Phil I did price a 600mm L series lens a few days ago. It was over 1,000,000 Yen.
