Fuji E550 not telling the truth regarding light?

    My understanding is that a given fstop, at a given aperture speed, at a
    given ISO, at a given ambient light level, should give a similarly
    exposed image regardless of camera. Correct?

    Well the e550 seems slow (darker) to me, by at least a couple of stops.
    In otherwords ISO 400, 1/60, f2.8 which should ordinarily be
    sufficient for indoor snapshots without flash (am I wrong here, this
    based on experience), but the e550 images are very dark.

    Irritatingly enough (though I suppose this goes with their ISO 800 mode
    which is only available on 3M images), the movie mode is sufficiently
    bright indoors, even though the still photos are not.

    Anyone else have this experience?

    Really?!? My recollection in the film days, was that if I have two
    cameras with the same film, and the same Aperture and the same shutter
    setting, I should get the same amount of exposure. If I needed twice
    the exposure you double the ISO, or you go down 1 full stop (f2.8 to f.2
    for instance), or you doubled the length of the exposure from 1/120th to

    Is this no longer true??? If not, why not?

  3. Don't know that camera, but "indoors" covers *many* f-stops of
    brightness range. I've certainly found ISO 400 inadequate for many
    indoor photos, and marginal even for brightly fluorescent-lit
    classrooms at f2.8 (I mostly had f2 or better available).

    A given ISO / shutter / aperture *should* produce pretty much the same
    brightness with any standard imaging system.
