Can I use a 430 EZ at 105 mm ?

Discussion in '35mm Cameras' started by Alexandre Montaron, Jul 18, 2005.

  1. Hello,

    I would like to know if I could use a Speedlite 430 EZ (which
    is normally limited from 24 to 80 mm) at 105 mm - fact more than 80 mm
    ?

    Is 80 mm a really upper limitation ? Can I take the shoot even
    with a less GN at this focale ? Will the EOS body stop-me in this way
    ?

    Thanks for your answer,
    Alex.

    You can use it at 500 mm -- but it's angle of coverage will still be the
    equivalent of 80mm which means that most of the light is wasted by being
    blasted in too wide a cone. If it still gives you enough light, go for it.
    The only time you really have to worry is at the wide end where, if the lens
    is wider than the flash you'll get vignetting.

  3. 430 EZ give 43 GN at 80 mm ... I suppose it will be enough for any
    need / purpose at 105 mm.
