Could you provide a short example? As I am not clear on how it works 
without seeing some code.

Better yet, update the wiki article.

Okay, I added some focal blur.

camera
{
	perspective
	up		Camera_Up
	right		Camera_Right
	location	Camera_Location
	direction	Camera_Direction
	focal_point 	Camera_LookAt
	aperture	4
	blur_samples	20
	transform {Camera_Transform}
}

But I don't see any difference in the object reflections like there is 
in UberPOV.
