3 day render, an old model of a standard 35mm camera lens, 99% rad lighting
(1 small very dim 3x3 area light)
blurred reflection created using a fine bump on ground plain (same settings
as image I posted a few days back)
spot the problem? I have no idea what caused that. nothing that an average
blur in psp wont fix mind
will post the post processed versions when I have it if any one is
interested

Awsome rolex? j/k :-)
Looks awesome! I'm just curious, if you put the POV-camera by one of those
lenses, would it give a sort of "camera" effect (lens flares, etc)?

You know, now that I look at it, the glass plate on the right lens looks a
bit too opaque to me. Is the scene lighting doing that?

The problem i see is in the darker parts of the reflection. It seems to be
"squared". After 3 days of render, this must be boring ... :)

yes - if you brighten you monitor up its really noticeable - and I have no
idea what caused it - as all my test renders didn't show anything like it

yes and no
the elements I made are rough approximations of the real things, mainly so
they look correct from the front. if I had made them a little more precisely
you would be able to look through them and get a semi meaningful result.
'real' lens flares are quite easy to achieve

Try putting an additional light behind the camera to see if that clears it
up at all. It seems like the shadows are getting "blocked up" by the "grip"
of the lens.
