Flash overexposure on a KM 7D

    Hi people,
    Got my new minolta 7D today and trying my older gear out on it. I notice
    that my flash, a 5200i program flash, appears to produce over exposed images
    with the camera, and I mean VERY over exposed, virtually no detail but a
    complete whiteout. This is on the Program setting which should, so I
    thought, make sure everything is just about right when using the flash set
    on TTL metering. Any ideas why this might be? My flash is about 10 years
    old but I thought it ought to work according to the sales people.
    Apart from this problem, all works just great so far.

    Secondary to this problem, I've just worked out that if I set the level to
    1/32, I get lovely images. I supposed problem solved in that sense but it
    seems the camera doesn't tell the flash when to turn off or something??

    Ah, the web is a wonderful thing. Found out more info. The way a flash
    emission is metered is different for digital cameras than it is with film
    (something I didn't know about 'til now!). With film, light bounces off the
    film and that is what the camera meters. With digital, as far as I can see,
    because light is reflected off a CCD a bit like a mirror, you can't do
    metering like when using film. Light output is apparently set dependant on
    the distance of focus determined by a specific digital lens (ADI capable) or
    by a preflash. I am not sure my flash is capable of preflash so I guess
    it's up to me to set the levels dependant on the situation, or buy a new
    Anyone add anything to this, or correct me if I am wrong?

    You need to use either a 3600HS(D) or a 5600HS(D) flash for ADI or TTL
    auto modes. Read the manual on flash compatibility.

  5. Looks like you have it figured out. I have an even older Minolta 4000AF
    flash from my film days, it will fire on the 7D, but no automatic
    exposure control. The 4000AF zoom head does react to the zoom lens on
    the camera, however.

    As Stephen pointed out, you will need a current model compatible flash
    for full functionality. I have one on my 'eventually' list, just don't
    shoot enough with flash to need it now.

    Yep, worked it out alright. Just do it manually, however painful it might
    be. Saw Ebay has a mint condition 5600HS(D) for $AU199 currently and I'm
    sure more will be available later on. The flash reacts to the lens on mine
    also which helps at least.
