Thanks for your input, but this is not the answer to my question.

Your answer would work if my 3D null’s z-position was zero, but it’s not.

Thanks Michael, I was trying to use this yesterday but I was running into other problems. I’m sorry you’ve had to post this response multiple times! I ended up using a few “toWorld” layer space transforms. With a few more expressions, I came up with a pretty functional and robust camera rig! I created that fake “POI” I was talking about by having the camera “lookAt” a ‘POI’ null. Focal distance was calculated using “length” from camera position to a ‘focal point’ null.

Thanks for your help, as well as Dan Ebberts’, who posted some other very useful layer space transform expressions elsewhere!
