What do you need the filmback for?

It cant be for tracking, because when you track footage you dial in your cameras filmback in the tracker and get a cg camera generated automaticly and with that a camera fov and image plane in your host app you can port over to octane automaticly.

The actual film in the camera, now days the sensor. The size of the media that's capturing the images.

@gk
as far as i know Octane uses the xfov. That's calculated:
xfov = 2*atan(0.5*filmWidth / focallength)
the more unusual fov is the yfov, maybe not that useful, but calculated:
yfov = 2*atan(0.5*filmHeight / focallength)
