Hi there,
I have a question about the Olympus 35 SP. My SP is 2 stops slower than my handheld meter. I know from the RC, that its not very complicated to adjust a meter. What about the SP? Is there anywhere a potentionmeter to adjust the meter?
Yes, I could turn the ISO dial 2 stops, but thats not the way I prefer...
Normally I shoot BW, so I don´t need 100% accuracy, but 2 stops is too much.
No, it has noting to do with battery problems. The SP was serviced some times ago and now a 1,5V battery fits.
Hope you can help, thanks for your time. If this would be a problem, the meter also would be faster with a 1,5V, not slower.

It is hard to say what your problem might be, however the 35SP had a very simple light meter sensor. It is a piece of sturdy cardboard onto which was bonded the light sensor. It will work fine, but I've noticed it sometimes loses accuracy...and there is unfortunately not a good substitute for it as this little piece of cardboard also contains a specially designed section meant to offer some modified spotmetering ability. Humidity seems to be a problem as this cardboard sensor is not glazed nor covered with clear epoxy or anything which would limit humidity's effects (those I've seen which had problems seemed to have suffered from oxidation). As for the adjustment that was made to use a 1.5v battery, well...there is not much I can say about this. It also could be the answer to your problem. There are many misunderstandings about making meters work with incorrect voltage sources. Have you removed the top plate to look inside? As I recall the potentiometer is in there.
