No assist beam with Canon Powershot S5 + Speedlite

Discussion in 'Canon' started by Jonathan Schneider, Jun 28, 2008.

  1. I've got a Canon Powershot S5 and as of yesterday a Speedlite 580EX II
    flashgun.

    Because I'd like to use the combination to capture subjects such as
    foxes I was hoping the flash's more powerful assist beam would errr
    assist in dark places but it doesn't come on.

    The camera's own (green) one still comes on. I have checked custom
    function 8 is 0.

    I'll check the assist beam with a friend's DSLR but am rather
    disappointed that it doesn't seem to work with this camera.

    Any ideas ?

    I don't own the Cano Powershot S5 (or any Powershot) to know much about
    it, but I can say that the SpeedLite 580EX II is the top_of_the_line of
    Canon flash. And in order to get the best out of the flash it will requires
    the combination of Canon Body's + Flash (sometime it may depend on the
    lens').

    IOW, the flash has some special feature's which only work with some newer
    Canon body (DSLR), and some feature may not work with some older or specific
    lens. Other than that it should work similar to just any regular flash, or
    if your body (camera) doesn't meet the requirement then then the special
    feature's won't be available.

    On some or all newer Canon DSLR bodies they have a button to fire a
    pre-flash for the beam to measure and adjust the power, which usually give
    brighter capture than without. And it seems like not all body works the
    same.

  3. Yes it's a top-of-the-line-flash so why is it I can sort out focussing
    in the dark by using a cheapo (red) laser ?

    The flash is top_of_the_line but the cemera isn't. Just like me I know
    thing a little more than I can express in English.

    And as I have mentioned, the flash can only does its best by good
    communication with the body and may be the lens, not just by itself. Or if
    the camera can't communicate with the flash then the best thing you can do
    is doing everything manually.

    If the camera can communicate with the flash then it will measure the
    distance, the background, the angle etc. to adjust the flash power to the
    best it can calculate. Now, without the communication then the flash just
    fire the light source, it can be under/over-flash depending on your setting
    or its guessing.

  5. But it obviously can and does communicate. Zoom, F-number, and power
    setting go through without a doubt.

    So why not "Oi you. Switch yer AS beam on please."

    Now the flash is capable of firing a pattern at the centre of the
    image (and other places) isn't it ?

    Maybe they simply forgot in the firmware. I'll ask them and hope it
    does good.

    With the newer technology and special features the combination of Flash &
    Camera can be a little more than than few auto option. That's why some
    older Canon DSLR cameras won't get all benefits from the Speedlite 580EX, or
    some DSLR has more/less option depending on the model's.

    Then beyond the auto you may need to go for manual for specific need. And
    as I have mention some DSLR has the button (* I think) to fire the pre-flash
    (different than the regular pre-flash) to give the beam a better chance to
    get a better measurement that it normal can't. So, if your camera has the
    " * " button then give it a try see if it's what you want. Other than that
    youy may have to question the camera instead of me <bg>
