    A new Sigma EF-500 DG Super ETTL flash showed up yesterday, so last night
    I hooked it to my DigiReb when some friends came over, and took some indoor
    shots. Nearly all of the them came out underexposed - anywhere from
    "significantly" to "majorly" underexposed. I tried both in Av and automatic
    modes, and both modes seemed to do about the same - most shots underexposed
    (subject and foreground), and just a few where either the subject was at
    least properly exposed, or (in a couple of cases) the entire scene was
    properly exposed. Any ideas why that would be?

    Just for fun, I shot the same scene with different flash modes to show the
    underexposure. The lighting is a mix of overhead fluorescents and diffuse
    daylight. This time, things worked relatively well in Av mode (although the
    Sigma was still a bit under). In auto mode, however, you can see what
    happens with the Sigma:

    I had a similar problem with a Jessops (UK photographic retailer) 400AF
    flashgun on my 300D. According to the literature it was supposed to have
    AF dedication, TTL mode, etc, etc. In reality the only way I could get a
    correct exposure was to set the thing manually.

    When I complained they tried with another flash and camera at the shop,
    with the same results.

    I ended up with a Canon 420 EX. I haven't yet used it a lot, but that
    appears to works well. It's nearly twice the price though..... oh well,
    it's only money!

    Regards,

  4. It may be twice the price but the right tool and the right quality tool are
    worth the cost.

    I think you may have a defective unit, or camera.
    I got the same flashgun yesterday and the results are superb!
