Cool I will try that thanks a lot!

You then need a "distance to plane" calculation... the distance from the
camera to null is the hypotenuse of a right triangle. The angle of that
line versus the z axis of the camera then gives you enough information to
determine the distance to the camera plane the null is on.
cos(theta)=a/h where
Yes it's working with the null centered. But what if I want the focus on
some moving object that is not always in the center of the camera and
coming near? It is like a follow focus rig.

Makes sense, thanks Tim!
That means that the info from the "Distance to Output Camera" is doing
exactly what you need Emilio, since when centered the ICETree info matches
perfectly.

Hey Ben,
the farther offset the null is off center to the center of the camera view
the more "off" the DOF would be because the DOF effect is sets in respect
to the viewplane of the camera and it would take some Pythagorean theorem
(http://en.wikipedia.org/wiki/Hypotenuse) to get the desired majo
Thx Ben.
The thing is the distance between node output is almost twice the distance
reported by the viewport. If I use the value of the Distance Between node,
the focus is farther than the expected. I am right now dividing the result
by 2 and I think I am getting there and getting the focus plane
It looks like "Distance to Output Camera" from the viewport options is
spitting out the info from a plane in front of the camera based on the
distance from the null if it were in the center of your camera's view. If
your null is centered, the values are the same from the ICETree and the
viewport in
Hello I am trying to rig the camera DOF so I can attach the distance to a
null. I am the ICE distance between node. But when I turn on the distance
to output camera from the viewer, it gives me a different result.
So the Distance to output camera from the viewport options is different
than the D
