Physically inaccurate DOF

Neilg: I’m getting noise but there’s no depth of field. Making the aperature that big effects the camera’s focus planes in the viewport, but stuff outside of them don’t seem to blur. Using a 1.0 aperature, and a small scene, stuff outside the planes is blurred as you’d expect.

Bobby: I tried the lens blur tool with a Z-buffer depth mask. Pretty cool! I like that you can just click different parts of the image and instantly change focus. The tilt-shift feature is nice too, although it doesn’t let you use a depth mask that I can see. The issue I have with the depth mask is that it seems to create sharp edges on objects of different depths, when it would be blurred in real life or with vray. Is that a limitation or is there a work around?
