Fukui-san today wrote a post today that gives a super-easy way to set the DP Merrill cameras to infinity focus. The original article is here:

The procedure is:

  1. Set the camera to Auto Focus.
  2. Turn off the camera.
  3. Turn the camera back on. When the camera restarts, focus will be set to infinity.
  4. Turn the camera to Manual Focus to ensure the shutter won't auto focus.

It works and it faster then manual adjustment. . It focuses past the infinity but may be they did it such that when you use aperture around f11 you still be able to blur everything but very distant objects.

ability to 'focus past infinity' is by design to accommodate potential temperature (climate) changes, which as you can imagine heat etc.. makes things expand (eg. lens elements) etc.. and therefore affect where 'infinity', as denoted by the lens barrel, really is.
