I agree, There seams to be a lot of work going in to the AFi, with the rotating sensor --and finally good black colors--. But the problem with SINAR, in my opinion, is that they seam to have too much money -as you say, they are part of Jenoptik, a huge company- and the seam not to know what is needed.
For example Sinar M. I don't want to make the mistake of talking about something that I have not research well, so I will just say that a dealer in one of the major back distributors said to me that this camera was not being desired by photographers at all. This was about 2 1/2 years ago. How much money went in to this system? Other smaller companies that need to stay focus to survive would have killed in the pre planing stages.
as far i know many electronic parts have been taken over from the sinar-m to the HY, it seems that this camera was a kind of technology carrier.
as you can see its still in the program, in 2008 appeared a new small battery and the 28HR adapted to it, which makes this camera to an excellent carry around tool with the best available 28mm lens on it.
i am little bit tired of all this speculations, about great new leicas and nikons and the beakdown of sinar and/or leaf and or mamiya and so on.
for me these companies seem to be alive but the new leicas and nikons dont exist yet..
so what will be in one or two years, we`ll see than,- these rumors arent helping no one.
btw. i just received the news that several accessories for the arTec are going to be ready soon.
it does not sound to me as if sinar is sleeping ....
