    The Canon EOS 450D / Rebel XSi (and other models) has a port to connect a
    wired remote control. The Canon model for the remote is RS-60E3. What I
    have found out so far is that this remote has 2 levels of pressing just as
    the taking button has, and this involves closing two contacts on the 3-wire
    connection of the remote to the remote socket. It uses 2.5mm plugs.

    What I would like to do is operate TWO cameras with ONE remote.

    It would seem that the obvious answer is to get Y-adaptor cord with a pair
    of 2.5mm plugs, and one 2.5mm socket.

    My big concern is any effect one camera might have on the other. I suspect
    this would not be paralleling the batteries directly, since such a contact
    should be very current limited by the acting circuit. But still, there could
    be some possible risk of damage if this is a sensitive circuit, and possible
    also a risk if mis-operation (for example parallel impedance could fool the
    acting circuit into thinking the contacts are closed, and it would behave as
    if the taking button were always being held down).

    Anyone know any accurate details on this, especially the internal wiring?
    Anyone ever tried this, such as for action stereo photos?
