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 !!!
Open the adapter. There are just the screw to unscrew
Put some WD-40 on the dark gray plate
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.
