LOL, no joke bagginsbill!  I've got my Canon 50D and a fast 2.8 prime lens sitting next to me... this is not close to what I can get with that equipment.  But the more I play the more potential I see.   A little depth makes a huge difference in the believability of renders. 

Good call on the pixel samples, that helps a lot but the more of this I add, the more I start to recall my older, slower computing days. 

What would REALLY help is if there was a way to lock that DOF "target" on the screen.  With photography I usually lock focus with the center AF point and then recompose to get the framing I want.  I find that very hard with Poser since the focus point vanishes as soon as I let go of the slider.
