Hi folks.
My Zorki 4K rangefinder window has suddenly become extremely blurry. Looking through it presents a similar image to looking through a very out-of-focus SLR viewfinder. I'm not sure how this has happened as it's been sitting in its case on a shelf since the last time I took it out to shoot.
It's not a misaligned rangefinder patch, the whole RF window is affected.
I have never taken a camera apart before, but I'd be up for attempting a fix if anyone can point me to some instructions. I'd hate to think that my Zorki might be dead when I've only put a couple of rolls of film through it!
