cheap fish eye lens on the thin lens camera

Sorry for the subject, it is my old house that I use to test various versions of OctaneRemder but, while I was working at an animation for a client, I have found an involuntarily
Fisheye effect and I wanted to play with it in a scene free of constraints to share with you.
basically the camera is "immersed" in a glass cube size 10x10x1 cm with specular material assigned.
Playing with the index and the focal length, you can play almost faithfully the
Fisheye effect with super acceptable rendering times. In the first tests I have played a bit with the value of reflection and activating and deactivating the dispersion that, in the end, I decided to keep active because chromatic aberration, which normally i hate, in this case, helps a lot to describe the effect.
here is the results, pure octane output, no post:

Cool effect and images.
Nice sky texture too.

interesting tests, Beppe =)
I'm just curious,
why not to turn camera fov to 180
& distortion to 1 to get fish-eye?

@prodviz: thanks
the sky comes from
here
@tom: good question
but for me is not exactly the same:
and probably because octane is so good and fast that is more funny, for me, to use a piece of glass in front of the camera and move it all around the house than using ps for mimic badly the effect... i'm not so good in post production

Those are some of the most realistic bricks I've ever seen. Nice work on those.

Pool -> no any caustics?! - but should use
PMC kernel (32-maxdepth (both diffuse and specular), ~120k-sample/px, no "caustic blur", 2000 rejects, parallelism 1)
water material for pool:
-reflection 0.6
-transmission 0.99
-dispersion 0.004 (must enable dispersion due to the real life
)
-index of refraction 1.32
Better and more much realism render.

ou, I see Beppe =) I though it was a case but I was in a doubt..(always thinking, maybe I miss something.. =)
p.s. I haven't said that previously, but the scene is very nice - so realistic/life like =)

oh wow! This is so cool!
It was a few weeks ago I was playing with the lens distortion, and wished I could distort more than it let me! This is great! All my renders are going to look like an old school skate or rap video now!
Thanks so much for sharing.

You're very stupid!!! I'm NEVER troll!! I have adviced to
@bepeg4d because his GTX 590 or 2xGTX 780 is/are much fast.
