I just bought a Krasnogorsk K-3 from ebay! And I got it at a rediculously cheap price!! I rule! Spike Lee, eat your heart out, baby.
For those of you who have no idea WTF I’m talking about, click.
Pretty!
Weird name, though. Looks like the sound someone would make while coughing and sneezing simultaneously.
Have you tried it yet? Last time I used mine, the film came back all jumpy. I haven’t gotten around to trying a different stock (I was using Ilford fine-pitch before).
I prefer my Eclair NPR, but it’s a heavy sucker.
Da, darling.
Anyone wanna make a movie? 
Nope, just closed the transaction, waiting for it to arrive in the mail. I’ve read that K-3’s are supposed to produce a VERY stable image, maybe yours needs a tune-up? The only other 16mm camera I’ve used is a little Bolex. It works pretty well, but the K-3 is just so damn cool!
Here’s something I got from the K-3 e-group apparently I’m not the only one with the problem):
Since other film has passed through this camera okay, I’ll try some Fuji stock when I get around to it.
I agree with you. It’s a fun little camera. The optics are great (but watch out for flares!) and I like the reflex viewfinder, which my Bolex didn’t have. The Bolex is a much easier camera to wind, however.
The original Russian case is absolute crap. I went to Ritz Camera and bought a hard case. It took a little arranging and I’d like to have more room, but it’s much better than the leather case it came with.
There are synch motors available but there are two problems: Once the motor is on, there’s no going back to the spring-wind; and even though the camera will be crystal-controlled, it will be way too noisy to shoot dialog with.
Enjoy! 
The best thing about them is that you get an instruction book entirely in Russian (I think there is a translation as well).
One of the cameras selling points is that it was used to make a Spin Doctors video? Yikes.
There is a manual in English on the site friedo linked. The .pdf version is much better than the .html version.
