Oh, BTW - I just checked and the 16mm Hologon G for the G-series cameras is available on Ebay for under $2K- multiple copies are listed in that price range. The north of $2K prices are folks being greedy hoping some sucker will come along and either be desperate and NEED one on a day they're the only one listed or be stupid and think, "well, if it's $4K, it must be better than the $2K versions for some undefinable reason".
