  Other problems with post-processing focal blur is that it doesn't work
correctly for reflections nor refractions.
  Also, true focal blur can add info to the image which is not seen in
a non-blurred image (eg. hidden surfaces can become partially visible).
Blurring a latter type of image afterwards will not add this info, naturally.
