ED? Any thoughts?
One user has posted a very thoughtful 3 part review at the film
scanners' list. The archive can be found here:

Is the claimed 4.2 ynamic range for real???
The OD number 4.2 is the dynamic range which could be accommodated by
14bit of RGB depth. Because of noise issues, this OD is certainly not
realistic for a single pass scan, but since this scanner is capable of
sampling 16 times, or even more if you use Vuescan, then OD=4.2 can
certainly be approached. Keep in mind however, the OD of films is
generally considered not more than 3.3, certainly not more than 3.6.
