    I have a dial set compur shutter and was wondering if there is anything special i have to do to get the thing to stay open when set on B or T. Is there some trick that I'm not doing or does this mean that my B and T setting is just broke? Thanks for any help you can offer.

    When you have it on B you need to keep the little lever pressed, or the cable pressed. When you have it on T you press the lever once to open, and once to close (or the cable). If on the T setting you press the lever and it does not stay opned then the T setting is broke.

    Yea thats how all my other shutters work, which is why I thought this one may be different. Both the B and T setting seem to be non-funtional, as both open and close reguardless of whether you hold the shutter down or not. Thanks anyway.

    Mine does the same thing. I use the shutter release set screw to hold open the shutter for focusing.

    Your cable release should have a locking knob or dial, just press it and lock it and you should be able to keep the shutter open to focus.

    Though not every cable release has a locking knob, in which case you'll want to get one.

    Oh i thought you were talking about a set screw on the shutter. The shutter will not stay open reguardless of whether the cable release is held down or not. The B and T settings do no work. Thanks though.

    I am going from memory now, but does this shutter have a wheel with the letters Z, C or the like?

    If so one setting is for the shutter speeds the other is for timed and bulb.

    Just had a look at mine (which works): A small wheel marked Z D M / T B I.
    When set to Z/T, it opens and closes using the release. Once to open, once to close.
    On the D/B setting, it stays open as long as the release lever is depressed (or cable release is pressed.
    Do not cock the shutter for any of these two.
    On M/I setting, the "normal" timed shutter is operating. Shutter must be cocked.

    Go to the S. K. Grimes website for this discussion about Compur shutters. http://www.skgrimes.com/compur/index.htm

    Down at the bottom of that page is a link to additional pages discussing how to operate each variety of the Compur.

    Sorry its broke. the shutter won't trip at all if its not cocked and in B or T mode. If its cocked in B or T and i trip the shutter it just opens and closes, even if i hold the release down. I think cocking it in B or T would cause damage with the similar compound dial set shutters, but not the compur ones. In any case mine don't work. :-(
