The hardware is perfectly capable of scanning a 40 mm wide piece of Medium Format film at 4800 dpi using the medium format film holders. The key is that the lens moves in and out - it can scan 60 mm width at 4800 dpi or 40 mm width at 3200 dpi. An existance proof of this capability is VueScan - set "Device|Mode" to either "MF 4800 dpi" or "MF 3200 dpi". > Also, on the subject of interpolation, it's debatable whether or not the > Scan Multi Pro is doing interpolation (as people usually think of it) to > reach 4800 dpi with medium-format film. It certainly is interpolating the CCD data from 3200 dpi to 4800 dpi. > Because it > actually extracts more information from the film at 4800 dpi than it does at > 3200 dpi. The stepper motor steps at 4800 dpi in this case. The stepper motor is actually capable of 9600 dpi stepping, and uses a divisor of 2 to step at 4800 dpi and 3 to step at 3200 dpi. Regards, Ed Hamrick
