Depth of field Phys cam question

V-Ray V-Ray for 3ds Max General

I’m trying to animate the changing of focus from far to near with heavy depth of field using a Vray Physical camera. I’m controling the focal distance with the camera and the problem I’m having is that as I change the focal distance the camera view moves ever so slightly. Is there a way to change the focus and have the view stay exactly the same using a vray physical camera?

Thanks.

That’s what you would expect a real lens to do. For what you trying to achieve, I would use post-prod DOF in a compositing app based on a static image, which would also be a huge deal faster.

Thanks, I’ll give it a try.
