    Bronica SQ-B mirror-lock-up failure.

    This afternoon as I was working with my SQ-B camera I suddenly noticed the shutter wouldn't fire; looking down at the camera body, the plastic lever connected to the mirror-lock-up mechanism had broken, and then fallen off.

    If you have experienced this issue, did only the lever need replacing or was there a more underlying fault?




    I'm guessing the replacement tiny plastic lever will cost £50 ...

    EDIT: I should add the shutter does appear to fire in the non locked-up position, but I've not put a test roll through yet.

    Christopher,

    Thanks for the repost. It can be rather unpredictable how these sorts of questions are replied to.

    I gues this is a push-knob.
    If you pull on it, does it release the mirror ?
    In that way you could be without an expensive knob.......

    Does the lever (or shaft) have a slot or index of some sort? It might be easy enough to fashion something from brass or "aluminium" with a set of files & a drill.
    Most likely the lever won't be that expensive. Depending on the technician it could be a freebie or couple of US bucks. Face to face dealing might be better than sending out. It's easier to charge more when you're not looking into someone's eyes.

    John,

    The disc seen in the photo does unscrew, there is a metal mechanism with a tiny bolt underneath, which the plastic lever connects to. My first reaction when it failed was why Bronica would use such a flimsy plastic part on a commonly used function.

    Bits from an ETRSi repair manual . . .

    So it's a little bit with a double "D" hole, I suppose one could do some creative work on an odd chunk of alumin(i)um with a file. It wasn't real obvious in the photo, but the round disk is actually a screw with a special head shape. Probably an easy do-it-yourself job if you can find a part.

    Some of them, yes, although I've not found the circular cap yet.
