baffling question for anyone who knows

    I work with a small team of researchers studying dragon fly aspects. We use
    small, mostly higher end, consumer camcorders to capture the flies in
    flight, mating, eating and whatever else comes up. Lately, we have been
    trying to study slow motion movement of the wings (much like slo mo
    hummingbird studies). However, we have been running into a problem. We are
    trying to record at the max of our camcorder, 60 fps, and then slow that
    down. The result is fantastic but only if we ":macro" the fly at 30" away
    (which allows the fly to almost fill the camcorder screen). If we try and
    record the flies up close, say 4" away, and still have plenty of light, the
    wings often appear steady or move in erratic ways. We can't figure out why
    when the wings are recorded and slowed down from a distance, they appear
    fine, but when recorded up close, they have non-movement or distortion.
    Does anyone here know and have a solution? We'd like to get some flies up
    close (without using the macro setting), but so far the erratic or
    stationary wing phenomenon has eluded us. Please help.

    Thanks in advance,
