A friend had a Canon digital camera using video floppy, I borrowed it and as I remember you had to hook the camera up to the serial port of your computer to transfer the images.
if you read wikipedia, apparantly there was 2 different 2" floppies around, one that indeed was digital formatted.

Another one, the LT-1, is digitally formatted—720 kB, 245 TPI, 80 tracks/side, double-sided, double-density. They are used exclusively in the Zenith Minisport laptop computer circa 1989
