    I've owned a number of film and flatbed scanners,
    and only two had focus control.

    Fixed Focus:
    Microtek 35t+
    Polariod SprintScan+
    Epson 1640SU
    Epson 4990

    Auto or Manual Focus:
    Nikon LS-8000
    ScanMate 5000

    The lowly 2720 lpi Acer Scanwit film scanner had/has automatic focusing,
    activated before doing pre-scans, and it also was the only scanner to
    have a direct light path from film to sensor, no mirrors at all. Not
    bad engineering, though limited by resolution. However, the Silverfast
    program for this scanner would overscan at 5,400 lpi. Move over,
    Minolta! {:)

    Hi false_dmitrii,
    I have inherited a large amount of 6x6 BW negatives, and some odd sized very
    old negatives which all do not fit in the KM-5400, so I'll probably need a
    flatbed anyway. But I'll wait patiently for the tests to appear...

    Is it done by film type, is it done visually? Did you focus above the film
    or below the film?

    It's completely automatic. You insert the film holder, ask for preview,
    and the scanner makes little ticking noises and the screen says
    'focusing...please wait', then after finding focus it does the prescans.

    Every time the carrier is inserted it does a focus sequence.

    Sorry, question incomplete; asking about Scan Mate ScanView 5000. Not just
    the focus check but relative to different B/W film (thickness, grain, dye,
    color, negative etc.) A book would do. TIA

    If you set it to autofocus, it will do this before each scan. It does
    this by looking at your target and then tries to optimize the
    contrast. If it cannot find enough contrast, the defualt value from
    the focus calibration is used. According to the manual it is
    particularly useful if an image is mounted with the emulsion side away
    from the drum so it would appear that the autofoucus compensates for
    any differences in film. Does this answer you question?
    You can also focus manually, just change the focus elevation after
    having done the initial focus calibration.
