That having been said, this is actually the premium feature of the OM-2
and 2n, if you think about it. The meter in the finder is an indicator
ONLY -- it actually controls NOTHING in Auto mode! It indicates the
_approximate_ shutter speed the camera will use assuming there's film in
the camera and a lens is attached (since the actual shutter speed in
Auto and Off Modes are step-less, you're not limited to just fixed
speeds).
It's the light coming "Through The Lens", reflecting "Off The Film" (and
at higher speeds, the pattern on the curtain, but that's another
discussion) that controls the exposure, _after_ the shutter is released
-- if the meter needle somehow controlled things, the 2 and 2n would
have been like all the other cameras of their era, using some sort of
memory system (trap needle, etc.) to pre-set the exposure _before_ the
shutter was released.
This also means that even if the meter does fail or malfunction, the 2
and 2n still work properly in Auto mode -- not a bad feature, if you ask
me! >>
Clintonr,
Thanks for the response, you make some good points here, but having cameras
fixed is too expensive when there is a no-cost way around the problem. I
have several bodies, one is off by one-stop toward overexposure, and one is
off by one-stop toward underexposure. the others seem to be OK. I thought it
would be simple to just set the ASA dial to accomodate the error and be done
with it. Now, I know doing that will throw the auto metering off. So the
solution is to simply mark the cameras and be aware when a viewfinder reading
is taken, that it is either OK, too high, or too low.
Now I will go back to sleep and wait for the auto exposures to go awry. I am
going to be shooting more chrome now because my scanner is malfunctioning and
it thinks everything, (both negs and slides), are all slides. This forces me
to scan negs as slides and then convert the image from negative back to
positive in my software to get a print. A major pain.
Regards, Paul Connet
