Dang HTML tags... I said 3D DOF. What Cinema does is apply a 2d post filter with the z-Buffer as mask, which does not produce accurate results. FireFly (and about any other REYES renderer on this planet) is performing accurate depth of field during rendering. but regardless of what Poser does do well, it's not in the same league as Cinema Just look at the price... But if you do a little research on render engines, you'll see that FireFly is rather comparable to Pixar's PRMan than Cinema 4D, as it is a REYES renderer and not a raytracer (note that until recently, PRMan did not do raytracing). Radiosity and HDRI are nice for architectural or car design stills, but not for character animation.
