Admittedly I'm JUST starting to play with this.  But are there any experts in the forum on this subject?  In my photography I often spend a lot of time dialing in the right f stop to get a nice background (and sometimes foreground) blur.  I was really excited to notice that option in Poser.  But wow, is it ugly right out of the box!  Does anyone know of a way to get an actual lens blur?  To me the default setting just look like a stipple painting... destroying not helping the feeling of photo realism.  If not, does anyone know how to render a depth map?  If I had that, I could use it as a layer mask and make use of Photoshop's very nice lens blur filter.  That isn't as elegant as a poser only solution but I could probably make due.
