    First roll with Petri FT1000, shutter gone? (pics)

    Hello good sirs and madames.

    Recently aquired a well-worn Petri FT1000 in more or less serviceable condition. Everything seems to work (note "seems"), but the test roll I shot is worrysome. Out of 36 exposures, 9 had issues. The film I used was Fuji Superia 200 with an expiry date in 2011 something.

    Due to my limited experience with film cameras I'm a bit at loss to determine the cause of the issues. If someone would be so kind as to have a look at a couple of the images and tell me what they think, it could be of great assistance.

    There are two different issues it seems. One is a part of the frame being overly dark, but not by the same amount from picture to picture. I am certain nothing (fingers, strap) was covering the lens. I'm guessing this has something to do with the shutter curtain thingy not working as it should, but the uneven edges do surprise me, would think they'd be perfectly even.

    I do not know the exposure data of this shot, but expo time was most likely in the area of 60-125th. The lens was a Carenar 35mm F/2.8. The lens does feel a bit.."stiff", in general operation, but the aperture blades do seem to open and close smoothly/lightly.



    The second image is what confuses me most. Here the whole frame is exposed but...ehum. WTF? (pardon my french) I'm thinking it might have something to do with the film transport system, no? Negative looks perfectly smooth and physically undamaged. Exosure data for this image is 250-500th, aperture unknown. Lens was a Carenar 135mm F/2.8. Lens appears to be in fantastic condition and everything moves as it should.



    Note that I got a number of good frames with either lens, but the partially-dark-frame-thingy seem to happen with both, the other thing I can't quite put a name to only happened with two frames, following each others with the 135mm lens. Any input would be very much appreciated.

    Ps. Pardon for the poor scan quality.

    You would be quite aware if the image had been obscured by a hand, glove, or some such. That being the case, I would suspect that the dark area on the first frame is the escapement mechanism of the shutter releasing the following curtain too quickly. Probably because of congealed lubricant and dirt in the mechanism.
    I have no guess to make on the other, except, perhaps, a problem with the processing.

    The one with the dark side is a classic shutter-in-need-of-a-CLA.

    The only thing I can come up with to explain the duck picture is high-level nuclear (or extra-galactic) waste dumped into the pond....

    Thanks for your input guys!

    I have already done some work with this cam, changing seals, cleaning the viewfinder/pentaprism and so forth. Haven't ventured into it's "neather parts" yet, but I will have a look at the shutter mechanism, try to clean it up and lubricate it a little bit. If it works it works, otherwise the cam goes on the shelf as a "pretty old thing" At least it's not one of those super-sensitive leaf shutters so mebbe I have chance.

    As for the second frame, I'm inclined to put dawn down onto a film loading/double exposureish thingy and most likely my error. I have a suspicion that I, in my eagerness, have yanked the film forward a bit too hard, thus causing problems. The nuclear theory has its merrits, but as the pond is 50 meters from the royal castle and therefore is royal property, I must admit I doubt it's a nuclear waste disposal area But hey...hmm...the russian embassy is not thaaat far away
