<div dir="ltr">I usually do the filtering in compositing, with the Z or mist pass, adaptively blurring from the focus point to the out focus parts. It works and it's hardly noticeable, in fact the bokeh shapes are still quite clear but with less noise. A more automatic way would be very welcome of course, specially since the mist pass doesn't have anything to do with the camera focus. <div>

issue of needing too many samples when using strong DOF effect.<br>I thought,
maybe for the out of focus samples could be somehow filtered/blurred similar
to what happens to glossy samples when they have filtering on?<br>This would
help probably best with the samples that are closer to camera that the focus
plane, while I guess it could be easier to do it for these?<br><br>A nice
example of the current problem can be the movie Whole by William
Raynisch.<br>While in this movie is the noisy defocus part of the visual
style, I guess most users would like the possibility to get a smooth DOF
effect...<br><br>I am also not sure if it is easy to detect the length of the
ray with glossy materials, so sorry if this is simply a bad idea
