    Using 500CM with duff mirror damper - bad idea?

    I have on hand a 500CM with clearly duff mirror damper (just a very few bits clinging on - more in hope than expectation)

    I'd like to run a couple of rolls through to test the general functioning of camera, lens and back, but I have a vague concern that this could damage mirror or mirror mechanism (or both) if the mirror is clattering back up without a soft landing.

    Am I being overcautious?

    (If I decide to keep the camera it'll go for a full service anyway)

    Couldn't you improvise a damping?

    This can allow the mirror to over-travel it's distance and jam the camera.

    I don't think it will cause any problems if you want to check the camera. However the mirror cushions that support the mirror in the frame are made of the same material so you may have focus problems. It is an easy fix!

    Mirror vibration or slap in a Hassie is one of the most common causes of lack of image sharpness. If the damper is bad, how do you know something else doesn't need attention on that body?

    This kind of begs the question of how are you going to decide whether or not to keep it if it's not working at it's maximum performance level? If you like it, keep it and get it CLA'd at a reputable shop. I'd do that first. They'll go through it and fix what's necessary to bring it back to spec (or as close as possible). When you get it back, THEN test it. ;>) and odds are you'll be really pleased with its performance and results.

    Take it light ;>)

    well, yes I realise all that, as I put in my OP

    On a point of pure (or perhaps perfect) pedantry, "Begs the question" is a corrupted usage these days; It doesn't mean "invites the question" or "the question must be answered", but is a formulation of a fallacy in syllogistic logic (in which the initial premise contains an implicit assumption of the truth of the conclusion)

    Beyond that existentialist hyperbole which I believe I'm possibly privileged to promote, is previously perfect pointlessly principled pedantry absent of all proper priority.

    As I enquired earlier: How can you tell if you want to keep it until you have it conditioned out of duff and up to snuff perhaps even buff?

    "Twas brillig, and the slithy toves Did gyre and gimble in the wabe; All mimsy were the borogoves, And the mome raths outgrabe. . .

    . . . 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe; All mimsy were the borogoves, And the mome raths outgrabe."

    from the Jabberwocky by Lewis Carroll.

    In addition to do the above it also performs as a light seal to prevent light from coming into the film chamber through the focusing screen/hood.
