OK, I hear you but:
1) why does that work and
2) how did you figure that out
I still don't understand. There is a progressive non -linear metering
error when metering anything but wide open that
is a f(aperture,?focal length). If the cam/chip know the correct
exposure at max aperture theoretically it could set a correct exposure
with stop-down metering if the chip then knows the manual lens f stop
inputted into the cam.
I have absolutely NO idea how that works accurately in AV but have a
suspicion it discounts the metering error issue. BTW it seems less on
the OM 5DII for some reason
and I have no clue with changed VF optics in the III if it is
different. I think I hear some Moose hoof steps in the distance. As
an owner of the emf chip and role as esteemed list logician all will be
clear soon, I believe.
