d70 - sync cord - iTTL-friendly

Discussion in 'Digital Cameras' started by Stanley Krute, Sep 17, 2004.

  1. Hi

    I'd like to put an iTTL-capable flash up on a bracket, and
    attach it to my D70 with a sync cord.

    [a] Do I need a special sync cord so that the iTTL will work ?

    Any sync cord recommendations ?

    [c] I'm guessing my Wein wireless stuff won't convey
    iTTL data. Is that correct ?

    Thanks ....

  2. i only know of the nikon sc-29 to support the ittl function. the older
    sc-17 does not. unfortunately the sc-29 is an expensive $75 in part because
    of the integrated infrared autofocus assist lamp. but i have heard
    arguments made for the use of ittl on a corded flash to be somewhat useless.
    i suspect that this is true when the flash is used in anything other than an
    on camera flash bracket as the distance information provided by the focus
    system could be inaccurate relative to the corded flash... hope this helps.
    ps. the sc-17 works fine otherwise. or just use the internal flash and set
    your sb-800 (?) as a slave and go cordless. no ittl in these configurations
    of course.

    I think it does (certainly it is ttl, and according to the manual i-ttl)
    provided you use the camera's flash in Commander mode (or, if you are
    lucky enough to have 2 SB800s, set the on-camera one to Master mode) and
    the slave in Remote mode.

    That in fact is such an easy way to get ttl flash that it is almost the
    only way I use mine. Cords just get in the way, unless you have such a
    tricky angle that it is impossible for the flash to "see" the camera
    even with reflectors.

  4. Thanks Christopher and Apteryx for the excellent info.

    Commander mode off of the internal flash sounds like
    the good way to go.

  5. This sentence comes from page 189 of the
    D70 manual:

    When an SC-series 17, 28, or 29 sync cable is
    used for off-camera flash photography,
    correct exposure may not be achieved using i-TTL
    Balanced Fill-Flash for Digital SLR.

    I'm guessing that the "may not" is there due to the point
    Christopher brought up:

  7. Gadgets noted:
    According to various posts I googled, when the built-in speedlight
    is used in Commander mode, its output is minimal.

    Yes, so minimal as to be useless as fill-in. It does no more than
    signal the SB800 and has no discernible effect that I can detect on the
    exposure. If in fact you need fill-in from the camera position, then
    you need either 2 SB800s or you need to set your SB800 to SU4 mode and
    you built in flash on manual (I assume without testing it that if your
    built in flash was on TTL, there would be pre flash problems)

  9. An SB600 as remote and an SB800 as master will do as well.

    Indeed there are preflash problems when the master is on TTL.
