My OM-1n has developed a strange behaviour.
- The meter activates on both "on" and "off" position. With lens on
open (5.6~2.8) and in the shutter range
1s~1/60 it acts as if metering the light, but does not *react* to
light. It rather sets itself to different fixed positions. In other
words it doesn't matter whether I point straight into a light source
or to a dark corner.
- The strange thing is that it does this even with the battery taken
out! So it must be some kind of mechanical fault.
- With battery: in daylight, with lens stopped down and in higher
shutterspeeds, it starts to react as normal to light changes.
- It may have to do something with the aperature lever on the body.
With lens off I can manually turn that and provoke the erratic meter
behaviour.
- The ASA dial is possible to turn infinitely.
- It doesn't matter what lens I try, so the problem lies not there.
I can deal with this "bug" in daylight, but in lowlight situations
it's hard to tell if the reading is accurate or if it's due to the
meters "own life"
Could it be some magnetic or spring-problem? Aperature-lever? Time for a CLA?
I found this advice from John H in the archives:
------
Every OM-1 body will display this behaviour. Remove battery, set ASA to
100, ss to B and lens to 1.8, needle centers.

Well I tried that and sadly it didn't work. With the settings
mentioned above the nedle is way up in the roof.
All this started two days ago, before that this beauty worked
flawlessly. What to do?
