Hi
I'm not a macro expert. MX is a "manual" camera all right, but it still has
TTL measuring at full aperture, using the Aperture Simulator in the camera
lens mount to transfer information about the aperture setting to the meter
circuit. Since the MX measures the light that hit the meter Throuht The
Lens, the metering should be accurate, as long as the lens has a "pin", for
the aperture simulator.
Best Regards
Jens

Hi,

how does a manual camera like an MX know what the correct exposure time is
with
for example a macro lens. As the magnification increases the eff. f-stop
increases
so exposure should be longer right? But the MX doesn't know the current
magnification so how does it do correct exposure time. Only thing I can
think of
is that a macro lens doesn't have an automatic aperture.
