3ds Depth of Field

axxic3

I am trying to set up a scene where I get a depth of field pass on a box, and the result is everything is blurry. The scene contains 4 photometric lights and a camera, with a plane as a backdrop. I've been rendering with mental ray, and set up the multipass effect for the mental ray depth of field. Looked through autodesks docs with no solution. F-stop is at 2.

Here's what I get: http://imgur.com/hTfbn5G

Finally figured it out, I had depth of field enabled both in the renderer (mental ray) and in the camera, made the whole scene blurry.
