As I understand it the lens has been going through continuing revision to get it optically and mechanically to the level that Phase One wants it to be before it ships. It will only be superficially similar to the Hartblei T/S on which it is based.
I will be doing some brief testing of the final pre-production version tomorrow, and expect to have a full production lens for testing and field use as soon as they are available, my guess is within a month or two.
If possible I'll post some initial impressions and shots from tomorrow's test before I leave for PMA and Zion on Wednesday.
