Zorki 4 shutter problem
Firstly, I should say that I have pretty much no hands-on experience with film cameras. I was born into the age of digital, and I don't know what overcame me to buy an old FSU RF. Anyway, I finally took delivery of a Zorki 4 and FED 2 today (I can't believe how cheap they are!)
I've come into a problem with the shutter release mechanism on the Zorki. I'll do my best to describe what happens, and I'd be extremely grateful if anyone can help me at all.
When I press the shutter down (usually faster speeds around 1/250), there's a half-click, as if the curtain moves slightly, and when I release my finger, then the shutter fires. I took off the back to observe this, and noticed that the curtain does in fact move a few millimetres when I press down initially, and then finishes firing when I release. I know that this definitely isn't normal because the shutter should fire in one smooth action; not an initial jerk, then normal fire.
(I can take a video of this if my description was too confusing.)
Does anyone know what I should do next? Is this a curtain tension problem? Or should I be trying to clean the firing/shutter mechanism as per the CLA guide (though I fear damaging my 'new' camera...)?
I don't think sending it to get fixed is really an option because I'm all the way down in Sydney. I am yet to put a single roll of film through it, and I want to get it right the first time. Any help would be greatly appreciated!
I hope this isn't the beginning of a very slippery slope...
