Hello,
My ASA disc was sloppy and when shaken it was giving about that 7 stops over
400ASA = 50000... Hence the probability of doing it. one of the back draw is
that usefull metering at F1.4 stops at around 2 sec@6400 or 1sec@12500
while in Automatic, after that we don't know ... my frame is a 1982, quite
old, but we see... also we have to know if it will be in the line of the
comparators.
The thing isn't really pretty, it requieres to modify the circuits them
self, we will have to insert couple of 0402 (.5mmx.25mmx1mm resistors) then
calibrate the whole thing and hoping to be still in an acceptable curve of
response, after that there is still hope but it might requiere a pre
amplifiying stage. That will be my job.
Philippe
