My Olympus OM-2n is 1 stop off compared to my Nikon F2 and a Nikkormat FT2. Does the OM-2n meter have a potentiometer that can be adjusted? If so, does anyone know where it is located?
Cheers,

Is this the meter in the viewfinder or the one that actually controls the automatic exposures? for the VF readout there is an eccentric that you can adjust, right next to the meter movement. it is reached by removing the top cover. adjustments for the autoexposure system are different and more difficult. |

Hi Rick,
Both are off by 1 stop. Do you have any suggestions for the autoexposure adjustment? |

the pot for adjusting the auto speeds is under the mirror box floor, between the 2 meter cells. adjustment is a bit tricky, not the least because it's very difficult to tell what speed you're getting on auto. if you put a speed tester in the film plane it has to be the same reflectance as a piece of film, and the lens has to be on the camera to give it the proper amount of light.
since the adjustment up on top is basically right on the VF meter movement and also the ASA dial, i'm not sure whether it affects the meter only or the ASA (which would affect both the meter and the autoexposure system). i would try adjusting that first, before i went digging into the pots under the mirror box, and see if it helps. |
