Since somebody else had mentioned earlier the dirty resister or something like
that, I had decided to do exactly what you suggested above. Since then, the
overshooting of the meter has not happened.
Otherwise my meter reading seems to be accurate. I tested it this evening by
using my OM-4 with the 85mm/2 on as a spot meter because as I was testing a
rented NPC Polaroid back on my Mamiya 6, I kept getting underexposed Polaroid
prints using the Mamiya's autoexposure mode, which gave a correct exposure
earlier in the day. When I used the spot-metered values and manually set the
exposure, I got a correct exposure. (I managed to remove the back door from the
Mamiya 6 on my own.)
Now back to the OM-4. I also have a funny LCD indication on the 4. Most times
when the meter is turned on, +- comes on even though the exposure compensation
dial is set to the neutral position. I have to jiggle the dial to make the +-
disappear.
Is this also related to any problems with the asa dial circuit board? As you
might know I did not pay too much for this ($175 including the 50mm/1.4 lens), I
am afraid that the store would be willing to have any repair done. Their policy
is if the repair is too costly, they would accept the return and refund the
money.
