View Full Version : Olympus 35SP spot meter problem?

09-21-2017, 23:10
Hey there! I'm new to the club: I've just bought an Olympus 35 SP - a camera I've been hankering after for a while!

One thing I've noticed however is even thought the main light meter seems to work ok, pressing the spot meter button doesn't seem to work; the needle just jumps to the right. I've uploaded a video here to illustrate: vimeo.com/234861409/0c717b50bd (https://vimeo.com/234861409/0c717b50bd)

Am I doing something wrong? Or is it screwed? I'm using a brand new Wein Cell MRB 625 battery (mercury replacement) which should be providing the correct voltage.

I don't think it's screwed but should be repairable. Usually the meters fail completely and then cannot be repaired as there are no more parts. But things like switches and buttons get dirt in them and that's not really a serious problem.

As it's a cult camera there are lots of people around who specialise in repairing them and have all the expertise and tools.

Not doing anything wrong, is the meter otherwise accurate?

It seems like the circuit that switches to spot metering is dead. I would open the top and see if there us a cable behind the button cut or disconnected.
See how to remove the top here:

Thanks for all the replies- I'll try open it up this weekend and see if it's something simple!

I couldn't find any info on the electronics in this camera when I repaired mine so I made some sketches and circuit diagrams (of sorts) describing how I thought it was supposed to be all wired up. Let me know if these would help and I'll try and find them for you.

I messed around with the wiring in my SPN for ages but in the end it was easiest just to transfer the entire working circuitry from a donor SP which was mechanically wrecked.
