Physical Camera, Focus Planes (DOF) Problem

Hi,

I am not sure if this a VRAY problem or 3dsMax.
When I set the focus/or-the-camera target on my subject as I see in viewport, it is not ever in focus on the render. (in terms of DOF)
I tried both “use the camera target” option and trying to set a custom focus and viewport display never matches the render.

The focus planes on Camera Cone,which shows where focus starts and ends, worked very well with VrayCamera and from the viewport I could easily set my target and can easily know the in-focus areas and where shallow DOF starts.
How do they work in physical camera?
Is this a bug or am I doing something wrong? Is there a workaround?

Solved the problem just after posting.
For that camera, pivot was at the midpoint of camera-target axis and was reading all the information accordingly.W
When I set to camera center, started to work again.

Checked this by creating new cameras and their pivots are fine so I must have changed the pivot for the existing camera without noticing.
