hi
we had a crew use this camera recently a couple of different times
one time they used a special converter on the front so they could use 35mm lenses, which i believe changes the film back width and height in that case.
( there is a preset for that in mm called 35mm 1.85 projection)
other wise if your using the standard lens then the film back is 8.8mm X 4.95
you will need to set the aperture width in your 3d program to 8.8 as well once you import your camera
hope this helps
