Greetings,
This would be my first post on these forums as I am stumped by some problems regarding the shutter operation on my recently-bought Zorki, so I thought this might be the place to ask 🙂
My problem is as follows: when operating the camera at lower shutter speeds, namely 1/25 and 1/50, the shutter curtain will not always retract as it should but indeed it works as if the shutter speed was set on "B", that is the curtain will only go back if you release the firing button. This usually happens when the camera hasn't been used for a while. This poses something of a problem because, well, you wouldn't want to waste frames if your camera was loaded now would you?
Apparently the shutter rights itself after some cocking - firing action and functions normally, which puzzles me because if the shutter mechanism was somehow broken wouldn't it act weird consistently?
I'm not all that familiar with the finer points of the mechanics involved in this particular type of camera, so I decided to snap a few photos of the shutter in the cocked and relaxed positions.
As you can see in the first picture, the curtain is smooth and apparently in order. This is the shutter in the relaxed position.
In the second picture it is cocked. You can clearly see this 'bump' or 'ridge' running vertically through the curtain. Could this be the culprit behind those pesky troubles? As far as I can reason, if the bump's too high maybe it causes some unwanted friction and therefore the shutter action remains incomplete.
Looks like a bad start for me with these Russian Rangefinders, so I would be grateful for any assistance you can give.
