Hey Tim,
I would use a expression.
open the exression editor-->Function-->Distance-->distance to camera
the result would be something like
ctr_dist_cam( null. )
null. would be the object name you're using to mesure the distance.
hope that helps

I'm trying to set up a camera rig that will let me use an item of some
kind (null, curve...) to act as a kind of focal point that can be
moved around the frame. Basically I want to have a control parented to
the camera which I can move around the frame, and which can be used to
create a vector between the camera and whatever surface is "behind"
that focal control. I'd then get the distance between the camera and
that point on the surface and pass that to my lens shader.
I'm really a noob when it comes to ICE in general, so I'm wondering
how best to do this. I suck with vectors...
