camera out of focus for good?

[soupastar]

Hello.
I have a great Yaschica Electro-8 that I have been using for a brief time (picked it up at a thrift store) it was working great until the last time I used it - I can't seem to get anything in focus through the viewfinder.
Everything just stays blurry.
Has this happened to anyone before?
What kind of trauma or lens problem could have caused this?
Thanks for any kind of comments or suggestions.

It's possible that your diopter adjustment was adjusted unbeknownst to you... check for a small know or dial near the viewfinder and adjest it while looking through. This focuses the viewfinder to your eye. In order to set it properly, open the lens up to the widest aperature, focus on infinity, and point the camera at something VERY far away, like a mountain or building downtown. Then adjust the diopter dial until it comes into focus sharply. If this was the problem you should be good to go.

Thanks for the tip. I did check the diopter but I may not have done it right. Your suggestions for adjusting it are helpful.
Thanks again.
