Kewl ..Sounds like what Im seeing here as well
I have two different sizes of Fuji's here
The tiny one that I got from Spec is 10mm by 12mm on each of the RGB faces
It has less loss but very small.
The larger one pulled from a Sony Betacam is 18mm by 22mm output face
aprox 22mm .. larger and easier to use.
The HUGE one pulled from an RCA film chain is too big to use and extremly lossy..Its justa show piece.
The smaller one has less loss , however I dont remember just how much less
Still..All very usable..
