I'm rendering a scene right now that involves a sphere, reflection, and 
focal blur. (Desktop image -- may post in PBI if wanted, its similar to 
a previous RSOCP image...)

It appears (unexpectedly) that the reflected scene in the sphere has a 
greater DOF than does the actual scene behind the sphere. Is this 
similar to some physical phenomenon? (I don't have a reflective sphere 
to see for myself) or is it just an artefact of the focal blur algorithm?

I'm curious to see if placing a lens in front of a camera that has focal 
blur turned on changes the focus of the scene behind the lens, but I 
haven't gotten to that experiment, yet.
