Hmm, in military aviation sytems integrations.we had a standing joke (from a
"technical expert") that 'it's just a bit of sheet metal work and a simple
software change". It never is of course.
The point I was making since Richard talked about other 24x36 CMOS sensors
is that both the M9 sensor and the required firmware are unique.
Leica Camera and Jenoptik might disagree with you that the firmware
differences are trivial. Or offer you a job. There's some millions of euro
in it.
Cheers
