1. Intro

Today i got a defectiv manual adapter for olympus om-10. The OM-10 has by default only aperture priority. But can turn it into a full manual camera with this adapter.

But i could not set any speed, just because it was stuck a 1/1000th of a second.

2. Figure out the Problem and solve it

I searched the internet to find something related. The most advised solution was to buy another adapter. I didnt want to go this way since it might be a problem easy to solve. so i went to the faecbook group "Learn Camera Repair" and asked if anyone else faced the problem. First response was an offer selling an adapter. Second response gave me an idea that the device used a little tiny metal ball to keep the set time in position. I thought, ok maybe this is just stucked in oil, grease or whatever.

!!! Advise in Advance: have patience !!!


  1. Open the adapter. There are just the screw to unscrew

  2. Put some WD-40 on the dark gray plate

  3. Move the dial a little now and then. After an hour i was able to set all times.

3. Going further

On idea i had was to make one adapter my self. In the repair manual for the OM-10 are all resistor values given to set each time. The Plug is a regular 2.5" mono audio jack which can be source at Mouser, Digikey or just from Ebay.

1. Overview

2. Dissambly

I started with removing the shutter dial. Move the plate clockwise and counter clockwise. Do not apply force, since it is just glued. Use Isopropyl if you can't get it moved. Do not bend it up.


There is a screw in the hole. Put a small screwdriver in the hole and unscrew it. Next, try to remove the screw, which holds the metal plate.


If it is stuck use a rubber band in between to apply more force. Take care, there is strong spring below and it will come up.


Now continue with the windlever. Remove the plastic plate.


Remove the white plastic.


Remove the remaining to plates and the lever


Next step is to remove the rewindknob. Fix it like shown in the picture, and turn the knob counter clockwise.


Remove the screw you see from above. If it stuck,....rubber band!


Now we start removing the hot show. First remove the plate above the screws.


Next, we unscrew the two encircled screws. Do not unscrew the other one. i did it,...and had a nice little puzzle.


Remove the last four screws....


...and lift up the cover. Here you go...


3. Assembly

There are some things to mention for the reassembly. You probably pushed the stick of the rewind knob down into the camera. Now you can't mount the wind knob. To lift the stick, get a proper tool....


...and place it under the encircled metal thing and pull it up. Another option is to open the bottom plate and push it up.


Next picture show how to place the plate on the shutter dail. The spring is not shown in this picture...


...but in this one.


Mind the notch on the plate...


... there is a hole in the ISO-Plate which fits there.
