    The "ttl" mode used by the SB-28 depends on the light being
    scattered off the diffuse surface of the film and sensed by detectors
    scattered inside the box between the lens and the film. The sensor
    (which replaces the film in DSLRs) is too shiny, and does not bounce the
    light in the diffuse manner needed, so Nikon had to develop an
    alternative systems which depends on a metering pre-flash (in the SB-600
    and SB-800 flash units) prior to the actual exposure.

    This also meant that the SB-28 could not work with the film N90s
    SLR after Kodak converted it to become a DSLR. The needed sensors were
    in the box between the lens and the film plane, but the scattering of
    the light off the digital sensor which replaced the film was incorrect,
    so it did not work properly.

    Wrong...the SB-28 did not work with DSLR's in TTL mode, but the
    SB-28'DX' was designed to work with DSLR's.

    yes, and because of that, nikon created the sb-28dx with d-ttl, which
    takes into account the difference between film and a sensor. the
    sb-28dx has d-ttl and will work fine on a d1x.

    however, d-ttl is no longer supported on recent nikon dslrs. they now
    use the much better i-ttl, and therefore, a sb-400, sb-600 or sb800 is
    required for those.

    O.K. I learn something new. So that is the flash which I would
    want if I were to go back to using my Kodak converted N90s cameras

    The SB28dx worked with the first crop of Nikon digital cameras, but with the
    D70 and everything since, it won't work in TTL mode. I know, I own one, and
    an SB-800.
