I just receive my Sputnik "in perfect working condition" which, of course, it isn't. I don't really want to send it back. The primary problem is that one of the shutters (left one viewed from the back) sticks open a bit. So when you fire the shutter, it opens 'instantly' but then is usually quite slow to close; i.e. you can watch the leaves slowly close, a bit jerkily. It would appear they just have some goop or something, but would appreciate any guidance. I will be taking it apart to clean and 'upgrade' the camera anyway, just making sure this shutter should be reasonably salvageable. Thoughts?
