For this one, camera blur is the definite culprit.  Without it, even with media
and photons turned on it takes a little over an hour.

I haven't done anything with tools to do post-production camera blur, so I rely
on what I can get from pov itself.  I like the way it gives me more photographic
rather than eye-realistic images, much as my hobby photography does.
