Hello,
as I am the OP please let me add one point which is quite important in my opinion:
I've written that above two days before I went to the Photokina.
There then Ive talked to the responsible product manager for the Leica M system. He told me that last year the sales for the M7 and MP have been a bit higher than in 2012 (1000 film M cameras were produced last year). They expect the demand for their film M cameras to be stable to slightly increasing in the next years.That is why they have introduced now a third film based M with the M-A.
AFAIK that is the first time in their history that three film M cameras are offered at the same time.
And also very positive: From next year on Leica will offer new courses for classic film photography at their Leica Akademie.
So both can be seen as a commitment from Leica to film and their film M camera production.
It is an important signal. And a positive one.
And maybe even a signal realised by other camera manufacturers (there were some rumors about that.....digital camera sales are in very strong decline

).
Best regards,
Henning
