I've recently bought a Yashica Mat 124, so I'm looking to sell my K1000 that I bought this summer, but something strange has begun to happen recently. The camera is in beautiful shape, with nice seals, a good meter, good times, it's clean, etc. But, when I use the 1/1000 second shutter speed, the shutter only opens half way before closing again, exposing only half the frame (and underexposing it, at that!). This isn't happening with any other speed. What could be going on?

Any ideas? Maybe I got swindled on the "it was recently CLA'd" claim... Or maybe I'm just unlucky.

These things happen. The most likely explanation is that the leading curtain is running slow. The fix is to lube and adjust.

Ok, thanks.

I tried a Yashica Mat 124G, too. Advise you keep your 35mm gear...

Really? Why is that?

I got the Yashica Mat thinking that, since my parents are getting me a DSLR for my college graduation in May (hoping for a K-5!), I probably wouldn't use a 35mm SLR much after getting that. I figured that having square format medium format would provide a different enough experience to keep film interesting, and I love the darkroom too much to let it go. I got the Yashica since, at $60, it cost less than a CLA on the K1000. I don't expect that it will be my only medium format camera ever; someday, when I save up some money, I'd like a Mamiya 6.

I had a similar problem when I started using my K1000, which was my mom's. I got half a frame at 500, & a bit less at 1000. Other speeds were fine. It was something to do with the shutter curtain sync, according to the repair guy (I think. It was quite a while ago.) A repair shop should be able to fix it up pretty easily.

Mine does this too - I just don't shoot at 1/1000
