    Actually, SLR cameras have the same kind of side-effects, although much less so nowadays. Look at old shots of racing cars, and you’ll see the wheels looking weirdly elongated (which coincidentally imparts a sense of speed). This effect was used subsequently by cartoonists, since the public had seen so many elongated wheels.

    It’s caused by a focal plane shutter, which (typically) moves sideways across the film plane. Since there are two curtains, one which opens and a second one which closes soon after, at higher shutter speeds you have, in effect, a traveling slit, scanning across the film. The subject is moving during the scan, so the image gets stretched or squeezed accordingly.

    These high-speed digital scan images are much more interesting though, and it’s an effect that is harder to achieve with the 1/8000 shutter speeds of modern SLRs.
