Never experimented with that, but...
Make the aperture small. Start with 1/10 of the smallest value that you
tried or smaller.
Do set look_at.
Make the focal point the same as the look_at.
Things on the plane defined by the focal point perpendicular to the
camera's location to the focal point vector SHOULD be in focus.
