Is it possible using POV-Ray to create (relatively) the same depth of
(optical) realism achieved in the following images?:

Is the current version of POV-Ray comparable to mental ray in all rendering
related features?

Thank you,

Those all are relatively unrealistic demo scenes of very low complexity. 
    It is no problem to create similar images with POV-Ray.  You can 
find a collection of examples of the render quality possible with 
POV-Ray on:

That question does not make any sense because the answer has to be 'no' 
for any two programs (just like 'Are apples comparable to peaches in all 
their properties?').  You can of course do a lot of thing with POV-Ray 
you can't do with mental ray.

  I don't see why not.

  POV-Ray is perfectly capable of producing images like those. You just
have to know how to set the environment (ie. everything that is
reflected on the objects), the lights and the textures/interior of the
objects properly. (I would probably start with fine-tuning the brightness
of the environment and the reflection exponent and specular roughness
of the textures.)

  I have never used that (or almost any other) software, but I would
assume that it might have some pre-defined texture and scene settings
which produce that kind of images and people might get sometimes the
(wrong) idea that that software produces better images than POV-Ray
because in POV-Ray there are no such pre-defined settings and they
might not know how to set them up manually.

  In fact, I once tried to reproduce two lightflow demo images simply
by trying to match lighting brightness and textures:

http://iki.fi/warp/pics/lftest2.jpg

  It's perfectly possible; it just requires perhaps more manual
fine-tuning than in the other software.

Crank up max_trace_level as needed.
